【Abstract】 Based on the 32kb/s ADPCMALGORITHUM suggested by the CCITT recommendation G. 721. This paper proposes using sixorder fixed poles instead of the two adaptivepoles, which are recommended by CCITT. This method can decreases the operation time and the performance of our algorithum satisfies the standard of CCITT recommedation G. 721. Hence this can reduce the number of DSP (TMS32010).更多还原
