source-channel
1.A general communication system, channel coding theorem and source-channel coding theorem.
3.A simple source distortion model is introduced to estimate the distortion ofsource coding, and the packet-based channel coding is applied to estimate the end-to-end channeldistortion. Two joint source channel coding strategies are proposed based on H.263 source codingand RS channel coding respectively.
4.The source-channel approach can be regard as a special case of maximum entropy approach.
10.According to "top-down" frame, the transmit subsystem is divided into 4 comparatively independent modules: time division multiplexing signal source, PCM encoder and decoder, channel coding (AMI, HDB3, CMI, disturbed code, 5B6B), digital modulation (2ASK, 2PSK, 2FSK, 2DPSK). The receiving subsystem includes the corresponding channel decoder, digital terminal (bit synchronization, frame synchronization, tapping), and serial interface communication receiving module.
