摘要
In this letter, we apply labeling diversity to a space-time block coded system, which does not require channel coding or bit interleaving. The proposed system is investigated for both Rayleigh frequency-flat fast and quasi-static fading channels. The theoretical average bit error probability of the system is formulated using the union bound approach. A possible optimization criterion for the design of the mappers for both M-ary quadrature amplitude modulated and M-ary phase shift keying modulated systems is suggested; however, due to a large solution space, a simple method is investigated.
