摘要： A multipath wireless communication is processed to recover a transmitted data signal without performing a direct matrix inversion (DMI). First, the multipath wireless communication is received. Then HHH and HHH values associated with the multipath wireless communication are determined. Weights based on HHH and HHH associated with the received data signal may then be determined and used to recover the transmitted data signal from the received multipath wireless communication.

摘要： A method for establishing wireless communication between a transmitter and a receiver in a wireless communication system is disclosed. The receiver includes an adaptive array that has at least two antennas. Each antenna receives a signal and produces a received signal. The transmitter includes at least two transmission channels for communicating the signal from the transmitter to the receiver. The wireless communication system suppresses interference at the receiver by applying an interference suppression technique when combining the received signals. The selection of a channel at the transmitter is based on the channel performance at the receiver for each transmission channel. The channel performance is based on a combining technique different from the interference suppression technique.

摘要： Equalizer training method using re-encoded bits and known training sequences. A multi-branch equalizer processing module is operable to cancel interference associated with received radio frequency (RF) burst(s) (e.g., using at least a first equalizer processing branch and a second equalizer processing branch). The first equalizer processing branch is operable to be trained based upon known training sequences and to equalize the received RF burst. The second equalizer processing branch uses at least partially re-encoded data bits to train linear equalizer(s) within the second equalizer processing branch. A buffer may initially store the received RF burst(s), which are retrieved and equalized by the second equalizer processing branch once the linear equalizer(s) are trained. The cooperation operation of these and other various components allows interfering signals to be cancelled and for more accurate processing of the received RF bursts to occur.

摘要： RF communications received by a wireless terminal from a servicing base station are used to determine the channel quality such as reported bit error probability (BEP). The RF communications may be in the form of RF bursts that are part of a data frame. An estimated BEP may be determined from the signal to noise ratio (SNR) of the RF bursts and or a sequence of soft decisions extracted from the RF bursts, and their historical performance. The SNR maps to an estimated BEP based upon the modulation format of the RF bursts. The soft decisions decode to produce a data block. When the soft decisions decoded favorably, the re-encoded data block produces a sequence of re-encoded decisions. Comparing the re-encoded decisions to the soft decisions yields a re-encoded bit error (RBER). The reported BEP may be based upon the estimated BEP, RBER, and/or RBER threshold. The RBER threshold may be adaptively incremented or decremented depending upon whether or not the RF communications were properly decoded. The size of the increment or decrement may be based on the channel quality.

摘要： A method to perform DC compensation on a Radio Frequency (RF) burst transmitted between a servicing base station and a wireless terminal in a cellular wireless communication system that first receives the RF burst modulated according to either a first or second modulation format. Samples from the RF burst, taken from the training sequence, are produced and averaged to produce a DC offset estimate. The DC offset estimate is then subtracted from each of the samples. The modulation format of RF burst may then be identified from the samples. Depending on the identified modulation format, the DC offset estimate may be re-added to the samples when a particular modulation format is identified as the modulation format of the RF burst. This decision is made based on how well various components within the wireless terminal perform DC offset compensation.
