摘要： A multi-user detector of transmitted signals includes a bank of despreaders and a processor. Each despread signal (produced by the despreaders) has cyclic and channel variations. The bank of despreaders despreads the transmitted signals to produce despreaded signals and the processor receives the despreaded signals and separately processes the cyclic and the channel variations. The processor includes a cyclic variation processor and a channel variation processor. The cyclic variation processor generally processes the cyclic variation of the transmitted signals and the channel variation processor communicates with the cyclic variation processor and processes at least the channel variation of the transmitted signals. The cyclic variation processor includes a weighting operator which weights the transmitted signals with at least one tap weight and a tap weight generator which generates the at least one tap weight at least from a cyclic code.

摘要： A method for communication includes receiving at a receiver from a group of two or more transmitters multiple Radio Frequency (RF) transmission beams that alternate in time and space and include at least first and second transmission beams.

摘要： A mobile user equipment includes a user equipment clock and a dual mode time tracker. The clock periodically wakes up the user equipment. The dual mode time tracker uses a serving cell reference signal to correct timing errors of the user equipment clock with respect to a network clock while timing errors remain minimal and otherwise uses a serving cell synchronization signal to correct timing errors of the user equipment clock. The dual mode time tracker also sets a next wakeup time as a function at least of the size of the timing errors.

摘要： A method for signal processing in a receiver includes receiving in the receiver a Multi-User Multiple-Input Multiple-Output (MU-MIMO) signal. The MU-MIMO signal includes at least a first signal, which is precoded using a first precoding scheme and is addressed to the receiver, and a second signal, which is precoded using a second precoding scheme. An average error rate achievable in decoding the first signal in the presence of the second signal is computed. The average error rate is computed over a set of possible choices of the second precoding scheme. The first precoding scheme is selected from among a plurality of available precoding schemes so as to satisfy a criterion defined over the average error rate. The receiver sends feedback to a transmitter transmitting the first signal. The feedback depends on the selected first precoding scheme and causes the transmitter to control transmission of the first signal.
