摘要： A method of a receiver determining the timing of a signal transmitted in a time-slotted manner, the signal comprising a sequence of information which is repeated at a known interval and has at least a known minimum length. The method performs correlation operations between groups of received slots of information, the groups spaced by the known interval. The groups are moved through the received signal, adding and removing slots, to locate a maximum correlation value sum for the group which should correspond to the timing of the slot. The method also can be used to determine a frequency offset at the receiver and/or an initial phase.

摘要： A communication structure and method which allows connection-like and connectionless communications to be provided on a multiplexed link is provided. The structure and method can make efficient use of available transmission capacity and/or network resources while providing both types of communication and hybrids. Connection-like communications can be provided by a dedicated code division multiplexed channels having allocated transmission capacity dedicated to the communication while connectionless communication can be provided by a shared orthogonal frequency division multiplexed channel through which data can be transmitted to subscribers. In an embodiment, the shared channel transmits inverse fast fourier transformed frequency sub-bands allocated to one or more of the subscribers. The allocation of the sub-bands can be fixed, or dynamically quantized or proportional.

摘要： A method of, and system for applying frequency-domain equalization in a DS-CDMA system, either by augmenting the transmitted data block before it is scrambled by appending a prefix and a suffix known to or knowable by the receiver or by augmenting the transmitted data block after it is scrambled but prior to transmission so that it has a scrambled cyclic prefix. In the former case, the receiver synthesizes one of the prefix, the data block, or the suffix that would have been received if the augmented transmitted data block after scrambling had had a cyclic prefix.

摘要： This invention discloses directional antenna systems, antenna combining and transmission antenna selection mechanism for wireless communication terminals such mobile handsets, mobile embedded laptops, mobile CPEs (Customer premises equipment), nomadic wireless CPEs, fixed wireless terminals and etc. The disclosed systems and methods only require analog circuitry and compass readings therefore are easy to implement and well fit into the current wireless terminals architectures. The inventive systems and methods resolve the problem that a directional antenna may not receive properly when user turn around and the antenna direction is deviated from transmitter; the inventive systems and methods further reduce the interference caused by omni antenna systems by selecting a directional antenna for transmit.

摘要： A radio frequency front end for a television band receiver and spectrum sensor includes a first plurality of adaptive matching networks connected to a signal summer that combines signals received by the first plurality of antennas respectively connected to the first plurality of adaptive matching networks and outputs a combined signal to each of a second plurality of downconverter/tuners. The downconverter/tuners are respectively or collectively connected to an analog to digital converter that converts output of the second plurality of downconverter/tuners into at least one digital signal that is output to the television band receiver and spectrum sensor.

摘要： Wireless devices, transmitters, systems and methods are provided that have a narrow band signalling channel and a wide band channel, for example an OFDM channel. In order to save power, the wireless device is nominally powered down with the exception of a receiver specific to the narrow band signalling channel. Once instructed to do so over the narrow band signalling channel, the wireless device wakes up the rest of its wide band receive circuitry.

摘要： This is invention discloses a perturbation antenna system for wireless communication terminals such mobile handsets, mobile embedded laptops, mobile CPEs (Customer premises equipment), nomadic wireless CPEs, fixed wireless terminals and etc. The perturbation antenna output is analogically combined with that of the primary antenna. The combined result is to re-create the antenna pattern shape and its direction pointing in order to achieve gains by user intercept. A variable delay circuitry is equipped to the perturbation antenna therefore the user's interception can be enforced via programmable apparatus either by manually or by digital inputs. The user can tune the delay parameters meanwhile observe the antenna pattern changes and the call quality until satisfaction.
