Abstract :
The effect of carrier frequency offset on the performance of BLAST-OFDM systems is presented. Analysis shows that system performance degrades as frequency offset and channel state information estimation interval increase. Numerical simulations confirm this conclusion. A pilot channel is recommended for synchronisation and phase-shift adjustment
