| Abstract: | Shape
coded modulation is a combined modulation and error-control coding
technique. The performance of a neural network decoder for shape coded
modulation is compared with a decoder based on a complex algorithm.
Simulation results over a range of signal-to-noise ratios (SNRs), for
rate 1/2 and rate 1/4 shape codes, show that a single neural network
decoder trained at a high SNR, provides near optimum results over all
SNRs. Abstract Number(s): B9710-6120B-056; C9710-7410F-039 |
