Wireless communication is an incipient technique to increase portability, but is inept on grounds of security and capacity. Wireless communication coupled with multiple access techniques help in resolving these issues and aid in providing variable data rates. The security aspects can be palliated by using spread spectrum with information hiding mechanisms. This study analyses confidential data hiding using spread spectrum scheme added to Orthogonal Frequency Division Multiplexing (OFDM) system adopting different modulation schemes. Performance analysis is done with and without confidential data embedding considering Additive White Gaussian Noise (AWGN) channel. Code Division Multiple Access (CDMA) are compared and analysed with Multicarrier CDMA (MC CDMA) schemes using Bit Error Rate (BER) performance.
