A fair level of speech quality is desired in speech transmission for mobile voice services. The effective utilization of bandwidth and higher bit rate is must for a best quality speech coder. But at a time the both requirements are not fulfilled in desired format. The research is ongoing in the area of designing speech coder's. In general the CELP is an algorithm to design a good quality speech coder. From 80's to present the advancement in this technique is going on. In this paper a wide band
