DS-CDMA in stego pitch

Wireless communication using multiple access schemes is the most challenging and rapidly developing field nowadays because of its advantages in security, increased capacity and its capability to cope with asynchronous data rates. Spread spectrum systems are combined suitably with multiple access and information hiding schemes to avail the consummate benefits in secret communication. In this paper, the performance of Direct Sequence Code Division Multiple Access (DS-CDMA) is analysed with and without information hiding in signal mapper block. The analysis is done based on the Bit Error Rate (BER) performance for single user system in AWGN channel environment using modulation techniques such as BPSK, QPSK and QAM.
