发明名称 Signal compression and decompression
摘要 A method of data compression, for example for image or audio signals, comprises encoding the data using a transform such as a wavelet transform or DCT, and transmitting only a predefined number of the most significant bits for each coefficient. It has been found experimentally that while such a method may marginally decrease the signal to noise ratio, the subjective quality of the received image or audio signal is nevertheless enhanced.
