Abstract

The V‐BLAST wireless communication architecture, space‐time block code (STBC), and space‐frequency block code (SFBC) techniques are strong candidates for achieving very high data rates in 4G broadband wireless communications. This paper extends the efficient Active Constellation Extension Smart Gradient‐Project (ACE‐SGP) peak‐to‐average power (PAPR) reduction method to STBC, SFBC, and V‐BLAST systems. Simulation results show 4.19 and 3.57 dB of PAPR reduction for the Alamouti STBC and SFBC, respectively.
