ABSTRACT:
In a method is disclosed for transmitting and receiving a transmission data signal, after the transmission data signal is generated, it is modulated by a first time spread root Nyquist filter to generate a transmission signal. The signal is then transmitted and received, whereupon the signal is transformed into a baseband signal. The baseband signal is then demodulated through a second time spread root Nyquist filter to revive the transmission data signal. An apparatus is also disclosed that performs this method. In addition, methods of separately transmitting and receiving signals are also described.
