ABSTRACT:
In a transmitting and receiving apparatus for transmission and reception of signals based on the frequency hopping spread spectrum scheme, hopping patterns used for a transmitter and a receiver are respectively constructed of frequencies which belong to the same frequency band and which are selected such that frequencies of both hopping patterns do not overlap with each other at the same instant and besides, there are provided a level detecting circuit for detecting a received power level of a received signal at each hopping frequency and a level control circuit for performing transmission power control for each hopping frequency by using information detected by the level detecting circuit.
