Multiple description coding for wireless channels with multiple antennas
نویسندگان
چکیده
Multiple description coding (MDC) provides error resilience by producing several descriptions of the source so that various quality reconstructions can be obtained from any subset of the descriptions. The use of correlating transforms within the MDC framework has been studied for “on-off” channels, such as packet-switched channels. Since this channel model is not appropriate for wireless systems, we introduce fading channel models, such as Rayleigh, Rician, or Nakagami channel, within the context of MDC. We further discuss the optimal correlating transforms. Keywords—Multiple description coding, source and space diversity, joint source-channel coding, and multiple antenna wireless systems.

متن کاملMultiple Description Coding with Multiple Transmit and Receive Antennas for Wireless Channels: The Case of Digital Modulation
Abstract—An effective way of providing error resilience with a relatively small reduction in compression ratio is multiple description coding (MDC). All multiple description codes to date assume the existence of multiple independent “on-off” channels between the transmitter and receiver. Each link is either broken in which case the symbols or packets are completely lost, or it functions properl...
