BEP analysis of OSTBC-OFDM systems with broadband pa and imperfect memory compensation

We analyze the performance of an OFDM system with diversity, in particular Orthogonal Space Time Block Coding (OSTBC) systems, including a broadband nonlinear power amplifier (PA) with memory. Closed-form expressions for the BER are obtained for cases when PA memory is compensated at the transmitter...

Zusammenfassung:	We analyze the performance of an OFDM system with diversity, in particular Orthogonal Space Time Block Coding (OSTBC) systems, including a broadband nonlinear power amplifier (PA) with memory. Closed-form expressions for the BER are obtained for cases when PA memory is compensated at the transmitter or the receiver. The results confirm that not only clipping noise, but also imperfect PA memory compensation has a significant impact on the system performance.
