Abstract :
We analyze the performance of a novel multiresolution joint source and channel coding (MR-JSCC) scheme for mobile radio channels with feedback. The transmitter and receiver can match the resolution of each other synchronously, according to the channel state information (CSI). Bandwidth requirements can be met by carefully adjusting the resolution thresholds. The threshold determination algorithm is outlined. Simulation results show that MR-JSCC scheme has much better performance than baseline-I (no UEP and no feedback) and baseline-II (UEP without feedback) at the same bandwidth and power
