Abstract :
The use of convolutional, BCH, and Reed-Solomon codes to improve the spectral efficiency of digital cellular mobile radio systems is investigated. Optimal code rates are obtained as a function of the allowable outage, under the assumption of ideal interleaving. The outage predictions themselves are obtained by computer simulation. Of the codes considered, the block codes are more effective than convolutional codes for improving spectral efficiency. One major problem observed with error-correction coding is its ineffectiveness for channels with very slow fading.<>
