Communication means transferring a signal from the transmitter which passes through a medium then the output is obtained at the receiver. Frequency hopping spread spectrum (FHSS) is a method of transmitting radio signals by shifting carriers across numerous channels with pseudorandom sequence which is already known to the sender and receiver. Finally, the chapter explains spread spectrum modulation (SSM) and orthogonal frequency division multiplexing schemes, which are especially suitable for the 3G and 4G systems, and elucidates how these techniques are superior to conventional digital modulation techniques.
