摘要： A wireless communication system for transmitting uncompressed video pixels from a transmitter to a receiver over a wireless channel is provided. The transmitter includes an interleaver that interleaves the video pixels into interleaved pixels, and an encoder that convolutionally encodes the interleaved pixels at the transmitter before transmission to the receiver. The receiver includes a decoder that decodes the encoded pixels, and a deinterleaver that deinterleaves the decoded pixels. When the video pixels include pixel errors, such interleaving and deinterleaving reduces pixel error clustering and improves video quality.
