Resumen:
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.
