Abstract:
1. A method for joint detection performed by a Direct Sequence-Code Division Multiple Access (DS-CDMA) system, the method comprising: acquiring a power of each of a number of codes in a matched filtering result of a received signal; adjusting a ranking order of the codes in the matched filtering result and a ranking order of column vectors in a system submatrix based on the power of the codes to obtain an adjusted matched filtering result and an adjusted system submatrix; and performing joint detection using the adjusted matched filtering result and the adjusted system submatrix to acquire demodulated signals corresponding to the codes, wherein, when performing the joint detection using the adjusted matched filtering result and the adjusted system submatrix, a first code is demodulated prior to a second code, and the power of the first code is greater than the power of the second code.
