Abstract
With the incentive of accommodating the highest possible number of speech transmission channels in the bandwidth available for digital cellular mobile radio networks the authors investigate a spectrally efficient, jointly optimised subband codec (SBC), Reed-Solomon (RS) codec, 16-level quadrature amplitude modulator (16-QAM) scheme. They discuss bit-error rate performance, and consider diversity techniques. A 5.3 kbit/s combined system is proposed, and its properties are described
