Equalization Techniques for Single-Carrier Modulations
Linear modulations use pulses to transmit data over a channel. Transmission through a nonideal channel (say, from multipath propagation) causes temporal spreading of the pulses. The temporal spreading of the pulses produces a phenomenon known as inter-symbol interference: the detection instant for a given symbol contains contributions from adjacent symbols. Equalization refers to the category of signal processing techniques designed to mitigate inter-symbol interference.
