Abstract:
1. A mobile communication system comprising: a transmitter that performs transmission of data at a transmission rate of 2400×(n+1) (n: natural number) [bps]; and a receiver that receives data transmitted from the transmitter, the transmitter includes: encoding means for encoding predetermined data to generate a binary signal; symbol converting means for sequentially converting the binary signal generated by the encoding means into a 2 a first base band filter that blocks an unnecessary frequency component of the symbol inputted from the symbol converting means and outputs a waveform signal; and frequency shifting and modulating (FM) means for transmitting a signal, which is obtained by shifting to modulate a frequency according to a magnitude of an amplitude of the waveform signal inputted from the first base band filter, to the receiver, the receiver includes: demodulating means for demodulating the signal transmitted from the transmitter and received and outputting a 2 a second base band filter that blocks an unnecessary frequency component of the 2 binary signal converting means for sequentially converting the 2 decoding means for decoding the binary signal inputted from the binary signal converting means and outputting the predetermined data, and wherein when a symbol of +(2 wherein the transmission path from the encoding means included in the transmitter to the decoding means included in the receiver forms a Nyquist transmission path.
