WebEmploy raised cosine filtering to reduce inter-symbol interference (ISI) that results from a nonlinear amplifier. Initialize a simulation variable for modulation order. M = 16; % Modulation order. Create square root raised cosine filter objects. txfilter = comm.RaisedCosineTransmitFilter; rxfilter = comm.RaisedCosineReceiveFilter; WebThis results in intersymbol interference (ISI), which means interference between the adjacent transmitted pulses. The term ‘symbol’ is a synonym for data bits or pulses in digital communication. As the name suggests, the symbols overlap due to the dispersive characteristics of the communication channels.
