In order to solve this problem, the paper brings forward an adaptive method—AMBTC(Adaptive Module Block Truncating Coding), the simulations prove that: The proposed algorithm has great improvement in terms of the construction of the image edges, this s.

By using modified block truncation coding and motion compensation technique based on one-step predictive motion estimation,the proposed codec can compress real-time videophone pictures below the bit-rate of 100 kbps on current PC.

Some experiments have proved that the combination of Block Truncation Codingtechnique and Subband Coding can get the reconstructed picture of a little raggedness ofsharp ed.

The block adaptive tree-structure vector quantization (BATSVQ) and the block adaptive predictive quantization (BAPQ) are analyzed.

In this paper, an adaptive coding technique is proposed, namely, adaptive Exp-Golomb codes (AEG), in order to mitigate the efficiency loss due to mismatch.

A number of methods are available for the compression of ECG signals, and the method presented is based on wavelet transform and adaptive coding that can reduce distortion in signal reconstruction with the compression rate being 5-12.

In next mobile communication system to suffice more and more high-speed data service and demand of Qos(quality of service) many new wireless link layer transport technologies are going to be used such as MIMO(multiple input multiple output), OFDM(Orthogonal Frequency Division Multiplexing), channel coding and ACM(adaptive coding modulation) etc.
