Preface
This book will address the subject of broadband communications using orthogonal frequency division multiplexing (OFDM). OFDM is a special case of multicarrier modulation (MCM), which is the principle of transmitting data by dividing the stream into several parallel bit streams and modulating each of these data stream onto individual carriers or subcarriers. Although the origin of MCM dates back to the 1950s and early 1960s with military high frequency (HF) radio links, R.W. Chang in the mid 60s first published a paper demonstrating the concept we today call OFDM. Chang demonstrated the principle of transmission of multiple messages simultaneously through a linear band-limited channel without interchannel interference (ICI) and intersymbol ...
