Abstract :
In this paper we propose the novel concept of embedding extra symbol to the CCSK modulation based TDCS signal. The embedded symbol is derived from the PSK mapping. The results show that as the constellation size of the PSK mapping increases, the CCSK BER performance improves tremendously. The embedded symbol improves the TDCS symbol SNR and consequently enhances the cross-correlation property of the CCSK modulation in noisy and faded channel.
