An efficient rate allocation algorithm for the progressive transmission of multiple images over time-varying noisy channels is proposed. The algorithm is initiated by the distortion optimal solution for the first image and searches for the optimal rate-allocation for each subsequent image in the neighborhood of the solution for the previous image. Given the initial solution, the algorithm is linear-time...
An efficient policy allocation algorithm for the transmission of embedded bit streams over noisy channels with feedback is proposed. The transmission is based on the type-II Hybrid ARQ/FEC protocol and uses a nested sequence C of channel codes to protect the packets. There are also constraints on the total bit budget and on the allowed number of retransmissions per packet. The allocation algorithm...
