Research on 8PSK + STBC + MIMO about High-speed Transmission Scheme in Mobile Communications

Abstract

According to BPSK¿STBC and QPSK¿STBC(Space-time block codes) wireless transmission system of two launch antenna and one or two receiving antenna, 8PSK+STBC high-speed wireless transmission system is proposed first in the research, and the transmission scheme is compared and simulated with Monte Carlo simulation from two aspects of noise performance and spectrum efficiency. The research results show that the scheme this paper has existed good noise performance and high spectrum efficiency that various schemes shows. 8PSK transmission scheme is still worth with application in the practice.
