N2 - This contribution considers the joint transmitter-receiver optimization in generalized multicarrier code-division multiplexing (GMC-CDM) systems. The joint transmitter-receiver optimization consists of an one-tap post-frequency-domain equalizer (post-FDE) and an one-tap pre-FDE. The one-tap post-FDE is optimized under the criterion of minimum mean-square error (MMSE), while the one-tap pre-FDE is optimized in order to achieve either the highest possible throughput or best possible error performance. Furthermore, an optimum spreading scheme is proposed for the GMC-CDM system, which is capable of achieving certain signal-to-noise ratio (SNR) gain in addition to the promised close-loop diversity gain. In this paper the performance of the GMC-CDM systems is investigated, when communicating over frequency-selective Rayleigh fading channels. It can be shown that our proposed pre-FDE and post-FDE algorithms are highly efficient, which are low-complexity and capable of enhancing significantly the error or throughput performance of the GMC-CDM systems.
