This practical book is an accessible introduction to Orthogonal frequency-division multiplexing (OFDM) receiver design, a technology that allows digitized data to be carried by multiple carriers. It offers a detailed simulation study of an OFDM algorithm for Wi-Fi and 4G cellular that can be used to understand other OFDM waveforms. Wi-Fi digital communications are based on several IEEE 802.11 standards. Extensive simulation studies are included using the transmission waveform given by the IEEE 802.11a standard. Shift ...

This practical book is an accessible introduction to Orthogonal frequency-division multiplexing (OFDM) receiver design, a technology that allows digitized data to be carried by multiple carriers. It offers a detailed simulation study of an OFDM algorithm for Wi-Fi and 4G cellular that can be used to understand other OFDM waveforms. Wi-Fi digital communications are based on several IEEE 802.11 standards. Extensive simulation studies are included using the transmission waveform given by the IEEE 802.11a standard. Shift register sequence for the scrambler, block codes, cyclic codes and convolutional codes are presented. Punctured convolutional codes for error corrections, large scale and small-scale propagation model are also included. Detailed derivations leading to the final formula for any algorithm are given, which allows the reader to clearly understand the approximations and conditions behind the formulas and apply them appropriately.
