Summary: 
This letter addresses the performance degradation due to carrier frequency offset in an orthogonal frequency and code division multiplexing (OFCDM) systems with multiple transmit antennas. For the performance evaluation, the average bit error rate (BER) expression is derived taking account of the effect of a carrier frequency offset. Derived results show that the BER performance of the space-time coded OFCDM system is less sensitive to a frequency offset, compared to the normal OFCDM system.
