Abstract
To enable an efficient implementation of multiple-antenna OFDM systems, this paper proposes an approach to reduce the influence of transmitter-induced nonlinearities in such systems. The approach comprises a preamble design, an estimation method and a digital compensation algorithm. Correction for the nonlinearities of the different transmitter branches is applied in the receiver, which requires no extra hardware. A numerical performance evaluation shows that the proposed approach can successfully be applied with minimal performance degradation compared to non-impaired systems.
