Abstract :
Polyphase fast Fourier transform (FFT) filter banks for quadratic amplitude modulation (QAM) data transmission are proposed. A previously proposed multiple carrier data transmission method is discussed along with its transient response. The transient response of the proposed polyphase filters is represented in a two-dimensional mesh plot with high resolution. Experimental responses are shown and discussed
