Abstract
A method based on modified sphere-decoding to compute the soft-information for the V-BLAST architecture is deduced in this paper. The system bit error ratio (BER) and computation complexity are simulated and compared with the classical methods. Simulation indicates that the new methods can reduce the decoding complexity with negligible performance degradation.
