M-ARY CHANNEL QUANTIZATION FOR SEQUENTIAL DECODING
Abstract
Sequential decoding with direct quantization of the M orthogonal channel outputs is investigated. The rate below which sequential decoding computations are manageable, is computed for a memoryless, coherent, gaussian channel. These computations show the direct quantization to be more effective than the list-of-l quantization, when sufficient storage is available in the decoding device. The performance of a continuous output channel can be approached by quantizing each output to only a few bits. The direct quantization of channel outputs also simplifies the cumbersome computations which would result if list-of-l decoding were implemented in a general purpose computer.
