Abstract

In this paper, the error performance of hierarchical quadrature amplitude modulation in layered space-time block code (LSTBC) system is investigated. Different hierarchical constellations are considered to obtain bit error performance over quasi-static Rayleigh flat fading channel. Comparison between BER in LSTBC system and BER in single antenna system is evaluated. BER performance with different priority vectors is also investigated.
