Abstract
A system (,) for digital processing of optical image data includes a wavelet decomposition unit (,) for decomposing an input image (,) into a plurality of frequency subbands. Each subband is then converted to a frequency domain representation, phase scrambled, and then converted back into a time domain representation in a phase scrambling unit (,). The subbands are then subject to trellis coded quantization (TCQ) in a trellis coded quantization encoding unit (,) before being transmitted into a channel (,). In one embodiment, fixed rate trellis coded quantization (FRTCQ) is used in a communications system having a relatively noiseless channel.
