OFDM (Orthogonal Frequency Division Multiplexing)
OFDM (Orthogonal Frequency Division Multiplexing). What is OFDM. Assume we need to send data at a speed of R symbols/sec. We break the data sequence into N (an integer, say, 48) sub-sequences. The data rate of each sub-sequence will be R/N, much slower than the original sequence.
