Pulse shaping is used in the implementation of digital communication systems to minimize ISI caused by nonideal channel characteristics and nonideal component implementations. Pulse shaping is performed in the transmit and receive filters of a communication system. The most common class of filters used for pulse shaping are Nyquist filters (1,2,3).
N2 - Generalized frequency division multiplexing is a non-orthogonal, digital multicarrier in areas like cognitive radio and machine-to-machine communication. steps upconversion, pulse shaping and upsampling as matrix operations.
