Abstract :
This paper presents a transmission scheme joining polynomial cancellation coding OFDM (PCC-OFDM) with space-time block-coding (STBC). PCC is a coding method for OFDM which maps data onto adjacent subcarriers, used here for reducing the sensitivity of OFDM to carrier frequency offset and Doppler spread. On the other hand, STBC is used to improve the error performance and increase the data rate of the transmission system. Simulation results have shown that the joint application of PCC with OFDM can significantly improve the overall system performance.
