Wavelet packet based multicarrier modulation is a technique combining wavelet analysis theory and multicarrier modulation perfectly. It improves the capability of system and adapts all kinds of environment. The error correcting code in this Wavelet packet based multicarrier modulation system (WPT-MCM) is RS code which is the best linear grouping code with a simple coding

At present, 3 G communication technology has matured and in some countries to enter the operational phase. 4G communication technologies are laboratory stage. ITU (International Telecommunication Union) has not been identified 4 G standards. Hiperlan/2 technology as one of the candidate standards has excellent passive transfer rate and transfer rates with the state. Error vector
