Abstract
A method for performing joint detection includes adjusting a ranking order of codes in a matched filtering result, and a ranking order of column vectors in a system submatrix according to the power. The joint detection is performed using an adjusted matched filtering result and an adjusted system submatrix, and acquires demodulated signals corresponding to the codes. The codes that have high power will be demodulated first. This ensures accuracy of demodulation, inhibits erroneous propagation effect, and improves accuracy of the joint detection.
