Reanalysis of BER for Wavelet Based MC-CDMA Communication

As demand for higher data rates is continuously rising, there is always a need to develop more efficient wireless communication systems. In this paper, described the author efforts in this direction. The authors developed and evaluated a wavelet packet based multicarrier CDMA wireless communication system. In this system design a set of wavelet packets are used as the modulation waveforms in a multicarrier CDMA system. The need for cyclic prefix is eliminated in the system design due to the good orthogonality and time-frequency localization properties of the wavelet packets. Wavelet Packets have good properties such as orthogonality and multirate flexibility, and have resulted in a number of works for its applications to code division multiple access communications.
