Digital signal modulating method for transmission on FM band, involves defining channels with bandwidth in frequency by considering preset minimum distance between channels, distributing each signal block in corresponding channel

摘要

The method involves separating digital signal into N block bn (1at most n at least N) and cutting useful frequency band (FM band) into N contiguous parts Pn. Channels having a bandwidth ln in frequency are defined by separating the channels in the corresponding part Pn and considering a preset minimum distance between the channels. Each block of digital signals is distributed in the corresponding channel. Independent claims are also included for the following: (a) a digital signal modulator (b) a digital signal demodulator (c) a digital signal transmitter (d) a receiver for digital signals transmitted on given frequency band.
