摘要： A signal detecting method and a receiver using the same are provided. The method includes the following steps. A receiving signal vector y is received through a number of channels, wherein the receiving signal vector y corresponds to a transmitting signal vector x transmitted by at least one of the channels. A channel matrix H is determined, wherein the channel matrix H represents at least one of the channels. A factorization matrix D is chosen, wherein D is invertible to make the channel matrix H expressed as H={tilde over (H)}D, and {tilde over (H)} is a corresponding channel matrix. The factorization matrix D is determined to make an expected value of the signal estimate error become smaller. The receiving signal vector y is detected to estimate the transmitting signal vector x according to the corresponding channel matrix {tilde over (H)} and the factorization matrix D.

摘要： A kind of folding systolic array architecture for a CFRS decoding circuit that applies to a cell search in a wideband code division multiple access system. The invention involves using a systolic array for its decoding circuit and using a kind of folding technology to reduce the area of the systolic array. The systolic array for the decoding circuit comprises an input pattern generator, a processing element array designed in the form of a systolic array and a boundary processing element array. Given the skewed-form output results required by the systolic array and generated by the input pattern generator, the processing element array makes a set of correlating comparisons, and outputs the results of the correlating comparisons to the boundary processing elements, so as to acquire the decoding results required by the CFRS decoding. The results indicate the frame boundary and scrambling code groups of the cell search in a wideband code division multiple access system.
