Block-based transceivers are widely used in wireless communication systems, mostly due to their well-defined structure and blockwise encoding. Interblock interference caused by superpositions of delayed signal copies is among their main physical-layer challenges, which is commonly eliminated with redundancy between adjacent data-blocks. Besides, channel equalization is also employed to further mitigate multipath channel interferences. The chosen amount of redundancy, however, may be overestimated, which opens an opportunity for reduced-redundancy superfast transceivers, whose key features include high spectral efficiency and low computational cost. Although superfast approaches aim at low complexity, proper equalizer-coefficient design and update procedures are still very intricate tasks, and most approaches are rather computationally cumbersome. This paper addresses such problem by proposing a new design strategy for reduced-redundancy block-based transceivers, which provides semi-blind equalization with data-selective update, in addition to the possibility of using redundant parallel equalizer structures, which are based on the use of fast Fourier transforms and one-tap equalizers. Simulation results indicate that the proposed methodology is effective and also able to achieve a performance comparable to what is obtained with state-of-the-art techniques, depending on the target application. |
