摘要： A multi-stage receiver and method for recovering a traffic signal embedded in at least one received signal. The multi-stage receiver includes a plurality of sequential detection stages for processing each received signal and providing successively better estimates of the traffic signal. The multi-stage receiver includes, for each received signal, a first processing stage and a second processing stage. The multi-stage receiver also includes a final processing stage connected to the second processing stages. Each first processing stage generates a first estimate of the traffic signal from the respective received signal and each second processing stage generates a set of energy values from the respective first estimate of the traffic signal and from the respective received signal. The final processing stage combines the set of energy values from each second processing stage and generates an improved estimate of the traffic signal. By employing multiple stages in the receiver, there is an improvement in successive estimates of the traffic signal.

摘要： A method and block detection receiver for detecting codes carried in a received signal processed into blocks of values. The method includes the steps of arranging the blocks into non-overlapping sets of at least two blocks per set; and for each set, executing a code detection operation over combinations of values, each combination containing one value from each block in the set. A single- or dual-maxima metric generator may be used. Preferably, the number of combinations of values is restricted and the values in a combination are weighted. The block detection receiver executes a form of sequence estimator. Accordingly, performance of the receiver is close to that of coherent detection and is much better than that of the conventional receivers which do not consider more than one consecutive block.

摘要： A SOVA decoding method determines, for each information symbol time and each state of a decoding trellis, a vector of probabilities for each possible symbol value in accordance with transition path probabilities for reaching the state with respective information symbol values and probability vectors for the states at the previous information symbol time from which the state can be reached, and also determines a total probability for each state. A soft output is provided by summing probabilities for corresponding symbol values all states of the trellis at an information symbol time relating to the start of the vectors, corresponding to a desired survivor path length. The vectors can comprise probability ratios instead of probabilities to reduce storage especially for binary signal decoding, and logarithmic probabilities or ratios can be used to simplify computation.

摘要： A correlation arrangement comprises 2k correlators each for correlating a sub-block of k symbols of a sequence derived from a received signal of a wireless communications system with all 2k possible sequences of k binary symbols to produce a respective one of 2k correlator outputs. For PN (pseudo random noise) synchronization, for each of N candidate PN sequences, a sub-block of k binary symbols of the respective candidate PN sequence is used to select a respective one of the 2k correlator outputs as a correlation output for the sub-block, and the selected sub-block correlation outputs are accumulated for m sub-blocks to produce a correlation result for a correlation block of mk symbols. A maximum one of the N correlation results is detected and the candidate PN sequence providing this maximum is identified for PN synchronization. N, k, and m are integers. The arrangement reduces computation for large values of N and large correlation blocks.

摘要： A method and apparatus for generating a frame quality indication of a frame of a received turbo encoded wireless signal is provided. A turbo decoder is used to decode a demodulated frame and provide a decoded frame. A turbo encoder is used to encode the decoded frame to provide a re-encoded frame. A modulator modulates the re-encoded frame. The frame quality is assessed based on a degree of correlation between the demodulated frame and the re-encoded modulated frame. The advantages include a less complex receiver due to reduced computational load, and potentially greater payload capacity in frames due to elimination of Yamamoto bits.
