摘要： A synchronizer of a fast frequency hopping spread spectrum receiver includes a correlator and a peak detection circuit for detecting the peak of the output signal of the correlator and outputting a detection signal. A sampler has the output signal of the correlator pass therethrough when the detection signal is outputted from the synchronizer. A code discriminating circuit discriminates the code of the output signal of the sampler. M pieces of frequency synthesizers of the correlator output M pieces of sinusoidal wave signals having the same frequencies as the frequencies of M pieces of carriers, respectively. A delay line of the correlator includes a plurality of delay elements connected with one another in a cascade, and delays the input signal of the correlator by each delay element and converts the input signal into M pieces of parallel input signals having different delay time, respectively. Besides, the delay time of respective delay elements is defined as a chip period. Each of M pieces of multipliers of the correlator multiplies one of M pieces of parallel signals by one of M pieces of sinusoidal wave signals which has been made to correspond in advance to the one parallel signal. A detection circuit of the correlator detects the output signals of M pieces of multipliers, respectively. An adder of the correlator adds up the output signals of M pieces of detection circuits.

摘要： A modulation apparatus is disclosed that enables significant improvements in signal transmission rate in a limited frequency band as compared with conventional modulation schemes. The modulation apparatus has first and second frequency-increasing single side band (SSB) modulators. The modulators are configured to have respective carrier frequencies with a difference by a frequency corresponding to the symbol frequency (i.e. fundamental frequency of the input symbol). An adder combines a lower side band (LSB) signal obtained from the SSB modulator set for a higher carrier frequency, and an upper side band (USB) signal obtained from the SSB modulator set for a lower carrier frequency to obtain a modulation signal.
