    摘要: A method and arrangement (100) for PRACH burst channel detection in a UTRA TDD wireless communication system in which training sequences are constructed from a single periodic base code. Unwanted cross-correlation peaks, having magnitude less than correlation peaks, are removed (440) from the correlator outputs, maintaining optimal signal-to-noise ratio of the channel estimates, providing a low probability of false detection, and extending the cell size of a CDMA network to that determined by the guard period duration. The cell size can be extended further by ensuring that no transmissions are scheduled for the timeslot subsequent to that in which the channel estimation bursts are scheduled.

    摘要: A method, NodeB (320) and User Equipment (330) for TDD operation in a communication system operating in TDD mode in a frequency band allocated for FDD operation. Preferably, operation is in TDD uplink and downlink mode in a first frequency band designated or normally used for FDD uplink communication, and in TDD downlink-only mode in a second frequency band designated or normally used for FDD downlink communication. The invention provides the following advantages: Provides a flexible method to deploy a time division duplex architecture in frequency division duplex spectrum. Allows flexible use of system capacity by adjusting the uplink and downlink capacity split. Removes previous FDD duplex restrictions.

    摘要: A cellular communication system comprises a Multiple-In Multiple-Out, MIMO, transmitter (101) and receiver (103). The MIMO transmitter (101) comprises a message generator (303) for generating MIMO messages comprising selected training sequences and transceivers (305, 307, 309) transmitting the messages on a plurality of antennas (311, 313, 315). The training sequences are selected by a midamble selector (317) from a set of training sequences in response to an associated antenna on which the message is to be transmitted. The set of training sequences is associated with the cell of the MIMO transmitter and comprises disjoint subsets of training sequences for each of the plurality of antennas. The receiver (103) comprises a transmit antenna detector (419) which determines which antenna of the MIMO transmitter the message is transmitted from in response to the training sequence of the received message.

    摘要: An efficient scheme for CDMA coding constructs codes by generating longer code sequences (430) via concatenation, from an existing set of short sequences (410, 420). The sequences may be spreading, scrambling and or training or channel estimation (such as midamble) sequences. The invention allows extension of sequences without performing an exhaustive search for sequences with optimal desired properties, as well as extension of the sequence duration to improve the detection of wanted signals via the use of a conventional matched filter, a multi-user detector or an adaptive filter/equaliser.

    摘要: The invention relates to an apparatus for measuring the heart rate and the respiration rate of one or more anesthetized rodent while monitoring and maintaining body temperature of at least one or more anesthetized rodent during diagnostic or surgical procedures. The apparatus includes a printed circuit board having four electrodes, two of which are injection electrodes and two of which are sensor electrodes. The heart rate is monitored through known electrocardiogram techniques, however, the respiration rate is monitored by injecting an electrical current across the chest of the rodent between two of the electrodes to determine impedance of the electrical current across the chest of the rodent. The impedance is carried by a respiration signal that is then graphically displayed to measure and, thus, monitor the respiration rate. The apparatus further includes the ability to maintain and monitor the body temperature of the rodent. Methods of monitoring the respiration rate of one or more anesthetized rodents during diagnostic or surgical procedures are also disclosed.
