Bit-wise arithmetic coding for data compression
Aaron B. Kiely · NASA Technical Reports Server (NASA) · 1994
This article examines the problem of compressing a uniformly quantized IID source. We present a new compression technique, bit-wise arithmetic coding, that assigns fixed length codewords to the quantizer output and uses arithmetic coding to compress the codewords, treating the codeword bits as independent. We examine the performance of this method and evaluate the overhead required when used block-adaptively. Simulation results are presented for Gaussian and Laplacian sources. This new technique could be used as the entropy coder in a transform or subband coding system.
