OFDM Receivers with Block‐by‐Block Processing

This chapter focuses on orthogonal frequency‐division multiplexing (OFDM) receiver design for individual processing of each block. Several receiver processing schemes are explained to accommodate the channel temporal variations within each block. First,The chapter discusses first focuses on a noniterative ICI‐ignorant receiver, where the ICI is treated as additive noise. Next, it talks about discusses a noniterative ICI‐aware receiver for communication over channels with large temporal variations, where the ICI is addressed explicitly in the receiver design. The chapter also provides a brief on iterative processing of the ICI‐ignorant and ICI‐aware receivers. It presents an ICI‐progressive receiver that adapts the ICI‐level to channel variations. Finally, the results of the ICI‐progressive receiver via simulation and recorded data from field experiments are analyzed.
