摘要： Pilot logic may determine channel information updates such as channel state information and phase correction information from pilot tones that do not travel close to the DC tone or the band edge tones. Logic may skip channel updates and phase tracking from pilot tones that have traveled close to the DC tone or the edge tones. In other words, logic may process the shifting pilot tones except for the pilot tones located adjacent to the DC tone and the edge tones. Logic may use channel estimates and phase rotations that are obtained from previous locations of the pilot tones instead of pilot tones that are adjacent to the DC tone or the edge tones. Logic may access memory to store the channel information such as the phase correction information previously obtained and the channel state information previously obtained and derived from processing pilot tones at locations adjacent to the symbol indices next to the DC tone and the edge tones.

摘要： By using an exclusive OR operation between two values to create a third value, a wireless communications device may communicate all three values to another device while only transmitting two of the values. In a particular embodiment, a bandwidth-static/dynamic parameter may be conveyed in a Request-to-Send by transmitting a length field and a scrambler seed to be used in the subsequent communication, with the bandwidth-static/dynamic parameter encoded into the scrambler seed. The receiving device may then derive the bandwidth-static/dynamic parameter by performing another XOR on portions of the two received parameters.

摘要： A system, method and computer program product are provided. The system includes a demapping element, and may also include a master controller. The demapping element is capable of estimating an amplitude of a signal constellation of a QAM signal. In this regard, the signal includes a pilot channel and a supplemental channel, where the supplemental channel includes traffic of a user and at least one other user. The demapping element is capable of estimating the amplitude based upon a power of a signal combination of a traffic symbol and a pilot symbol. The system can also include a master controller in electrical communication with the demapping element. The master controller can then be capable of demodulating the traffic of the user in the supplemental channel of the QAM signal based upon the estimate of the amplitude.

摘要： A wireless receiver stores one or more frames of received data and, during an initial demodulation, resolves each individual path for the multipath channel and estimates (pilot) channel parameters in order to process the received traffic, then preferably decodes the processed traffic to produce an estimate of the transmitted data. The estimated data is re-encoded exactly as encoded by the transmitter, then scaled and time-shifted utilizing complex weights and timing estimates garnered during the initial demodulation process. For each resolvable path, all other paths are time-aligned to reproduce the interference detected in the original received signal, with the resulting information employed to cancel the interference from other paths. Once all paths have had interference from other paths canceled, the results are combined and again decoded, re-encoded and reprocessed iteratively until residual interference and/or decoding errors are eliminated.

摘要： In a CDMA cellular system, a method for estimating the amplitude of a traffic channel based on a pilot signal received from two or more basestations. Each channel in a RAKE receiver is provided with a data signal received on a traffic channel and a pilot signal received on a pilot channel. A comparison is made between the product of the pilot signal and the data signal versus the product of the pilot signal and an estimate of the traffic channel amplitude. The estimate of the traffic channel amplitude drives a feedback loop to refine the comparison and the data signal is weighted by the traffic channel amplitude estimate and combined with weighted data signals in the other channels of the RAKE receiver.

摘要： A method and an apparatus for encoding of trellis coded direct sequence spread spectrum communication signals are provided. An input data bit sequence is received into a transmitter where it is encoded and modulated using trellis code modulation. The encoding comprises encoding the signal using a convolutional coder having a rate equal to 1/log2 (M), where M is a number of biorthogonal Walsh sequences. The encoded and modulated signal is spread by mapping a number of branches of the trellis code to a number of biorthogonal Walsh sequences. The mapping comprises labeling the branches of the trellis code using the biorthogonal Walsh sequences. This mapping uses the output of a convolutional coder as a memory address where the memory address contains one of a number of biorthogonal Walsh sequences. The spread signal may be a binary phase-shift keyed (BPSK) data signal, but is not so limited. A pilot signal is embedded into the spread BPSK data signal to provide phase coherency between the reverse link transmitter and receiver. The BPSK data signal is then multiplexed to form a quadrature phase-shift keyed (QPSK) signal. The QPSK signal is spread using a pseudo-random noise (PN) sequence prior to being transmitted.
