Abstract:

The goal of this program was to integrate the error-resilient set partitioning in hierarchical trees ER-SPIHT video codec into a system for transmission over an orthogonal frequency-division multiplexing OFDM channel with rate adaptation. The bit stream from video codec should be distributed among the subcarriers for optimum throughput with minimum probability of decoding error.
