The subjects uses an improved ADPCM algorithm, not only improves the speed but also reduces the occupied FPGA resources and the cost.
课题中采用了改进的ADPCM算法,不但速度得到提升,而且FPGA占用资源减少,成本大大降低;
This paper proposes a new method of interframe ADPCM Coding based on MSEP of last field, which gives design parameters of three predictors and five quantizers by five typical image.
Based on the feasibility study and the analysis to the encryption algorithm, the paper presents a method of the real-time multi-point voice communication in network, which USES ADPCM and UDP.
