Abstract: PURPOSE: A method for performing frequency hopping is provided to digitalize all signals for the frequency hopping in a base band so that a frequency hopping band diffusion communication system can be noise-proof. CONSTITUTION: A frequency hopping code 'c(t)' is generated. Information data 'd(t)' to be transmitted is allocated to K numbers of channels(k=0, 1,..., k-1) according to the generated frequency hopping code, and mapped as a signal according to a specific mapping pattern to output the signal as a signal X(k)(k=0, 1,..., k-1). The mapped signal X(k) is performed by a reversely fast Fourier transformation and outputted as a signal x(k)(k=0, 1,..., k-1). The transformed signal is converted into a serial signal 'dm(t)'. The serial signal is boosted by using a fixed carrier frequency 'e(jWct)'.
