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.


Linear, single-carrier modulations are described by the complex-valued, low-pass equivalent pulse train (Proakis 2008).
$$ {s}_c(t)=\sum \limits_{k=0}^{K-1}{a}_k{p}_c\left(t-{kT}_s\right) $$
