نویسندگان
چکیده
Recently, the multiple-input multiple-output (MIMO) schemes have been proposed as efficient solution for future wireless system. MIMO schemes can achieve a significant increase in the bandwidth efficiency as well as an improvement of the transmission reliability. In this paper, switching for the detection schemes based on channel condition is proposed in MIMO system. The QRD-M detection scheme has better performance and high complexity than the QRPIC detection scheme. Two detection schemes are efficient switched based on channel condition. Therefore the proposed detection scheme has little performance degradation, but it has low complexity.
