apparatus and method for improving the symbol-error probability performance of M-ary Phase Shift Keying system having an quadrature error

摘要

M-PSK (M-ary Phase Shift Keying) with a quadrature error of the symbol error rate performance improvement system device and method are disclosed. The apparatus using the quadrature error and at least one of the first received symbol pair , conversion parameter detector for detecting a parameter for converting a symbol determination region; And the conversion using the detected parameters and the second transformation to the received symbol pair , the transformed symbol pair of the converter and to determine to determine the transmitted symbols according to a code characterized in that it comprises a . According to the present invention , MPSK can improve the problem of signal degradation symbol error rate according to the error in the quadrature demodulation , it is a simple way to estimate with a quadrature error .
