VII Network Layer or Steam Layer Design] Besides the throughputs achievable by hierarchical modulations, it is also interesting to understand hierarchical modulations from a practical signal-processing perspective. At this time, the performance of hierarchical modulation will be evaluated through an actual implementation, where demodulation error is one of the

VII Network Layer or Steam Layer Design] Hierarchical modulation, also called layered modulation, is one of the techniques for multiplexing multiple data streams and modulating them into one single symbol stream, where the base-layer symbols and enhancement-layer symbols are superimposed before being transmitted. When hierarchically modulated signals are transmitted, users with good
