Abstract :
Distributed video coding (DVC) promises good quality with low complexity transmitters. However, previous research on DVC mostly focusses lossless channel, i.e., parity bit stream is not influenced by channel noise or distortion. This paper considers DVC over realistic wireless channel with noise and multipath fading. Note, errors in the parity bit will severely impair the system performance. We consider multiple input multiple output (MIMO) based diversity scheme to overcome the channel fading. BER and PSNR performance show that with MIMO, DVC can suitably overcome wireless channel impairments. We also determine the best transmit-receive antenna ratio for the DVC codec with more complexity at the receiver.
