摘要： A system and method for resource management and traffic control in time division duplex communication systems. A multi-radio base station maintains communication links with a plurality of remote terminals, each of which requests a specific bandwidth ratio. A controller analyzes the requested bandwidth ratios and allocates slots in the base station radios according to a packing scheme that synchronizes the transmission and receive timing of the multiple base station radios communication links. The resource management and traffic control techniques may be applied to a variety of communication devices communicating over a variety of interfaces, such as WLAN or a BLUETOOTH short range communications technology interface. Furthermore, the techniques can be employed with devices communicating with two or more remote devices via different interfaces.

摘要： An entire radio transceiver can be completely integrated into one IC chip. In order to integrate the IF filters on the chip, a heterodyne architecture with a low IF is used. A single, directly modulated VCO is used for both up-conversion during transmission, and down-conversion during reception. Bond-wires are used as resonators in the oscillator tank for the VCO. A TDD scheme is used in the air interface to eliminate cross-talk or leakage. A Gaussian-shaped binary FSK modulation scheme is used to provide a number of other implementation advantages.

摘要： A system and method for conserving power in a radio communication network wherein a radio receiver periodically scans for a transmitted signal. If a signal is not received after a predetermined period of time, the period between scans is increased. In a multi-unit system, the scan periods are offset from an absolute time reference to prevent more than one unit from transmitting at the same time.

摘要： Transmission power in a frequency-hopping radio system that transmits packets from a sending radio unit to a receiving radio unit, wherein each packet includes an address designating the receiving radio unit, is controlled by measuring received signal strength of packets whose addresses were successfully received in the receiving radio unit, regardless of whether other portions of the respective packets were successfully received. An average signal strength value is generated from the received signal strength measurements. The mathematical difference between the average signal strength value and a target value associated with the receiving radio unit is then determined and used as a basis for deciding whether to send a power control message from the receiving radio unit to the sending radio unit. In order to provide a hysteresis in the power control process, a power control message is sent from the receiving radio unit to the sending radio unit if the mathematical difference is greater than a first decision boundary, or if the mathematical difference is less than a second decision boundary. The power control message may itself include the mathematical difference which, when received by the sending radio unit, is used as a basis for determining a transmission power level adjustment amount. The target value, against which the average signal strength value is compared, may be based on the receiver sensitivity adjusted to account for implementation losses and other inaccuracies.

摘要： A frequency hopping generator comprises an XOR processing module and a PERM (permutation) processing module arranged in series. The XOR and PERM modules act directly on input clock lines as a function of a selection address. The hopping number sequence generated by the frequency hopping generator can be changed in real-time by changing the selection addresses, while the phase of the sequence can be changed in real-time by changing the clock value on the clock lines. The frequency generator finds exemplary use in rapidly switching between different piconets in a wireless scatter network.

摘要： A first wireless unit engages in contemporaneous participation in a plurality of wireless networks. A connection is established with a second wireless unit in a first wireless network. Then, a hold time-out period is determined, and the first wireless unit enters a hold mode with respect to the first wireless network. While in hold mode, the first wireless unit establishes a connection with a third wireless unit in a second wireless network. This may include the first wireless unit paging the third wireless unit and acting as a master unit in the second wireless network. Alternatively, the first wireless unit may periodically listen for paging messages from a master unit, and respond when paged, thereby becoming a slave in the second wireless network. The first wireless unit then participates in activities in the second wireless network. Upon expiration of the hold time-out period, the first wireless unit resumes active participation in the first wireless network. This may include determining a second hold time-out period to be used in connection with the second wireless network, and entering a hold mode with respect to the second wireless network.

摘要： The invention relates to synchronizing in communication systems by using a sequential correlation technique. A digital sequence known to the receiver, a so-called signature, is allocated a plurality of segments. The segments are correlated, segment for segment, in a correlator (300) which is equally as long as the segment. The segments may have the same or different bit patterns. When a first segment is received in the correlator (300) and the correlation value of this segment exceeds an associated threshold value, the segment is accepted as received and is saved in a memory (308) in response to a signal from the control unit (311). A timer (319) is set to a time point that corresponds to the length of the segments. There is then correlated a second segment whose correlation value on the signal from the timer (319) is added (304) to the value stored in the memory (308). If the sum exceeds an associated threshold value, the sum is stored in the memory (308). Detection continues in this way. When the sum of the correlation values of all segments have exceeded the threshold value of the last segment, there is generated a sync. time pulse signal (Ts). Should a threshold value not be exceeded, it is assumed that a wrong signature has been received, and detection of the first segment is recommenced.
