IPC: H04B1/713
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To reduce the deterioration of transmission quality owing to interruption when the same chip is hit at the time of multiple access by means of an FFH(fast frequency hopping) system. SOLUTION: An idle chip insertion part 33 sets one chip to be the idle chip of power 0 at every symbol in the carrier output of every chip, which is outputted from a frequency synthesizer 32. Transmission digital information is spectrum-spread and transmitted by the carrier with the idle chip. On a reception side, an interference chip discrimination part 42 checks the power of an idle chip position in a signal which is inversely spectrum-diffused by a frequency synthesizer 44. When power exceeds a prescribed threshold, a hit is judged to be generated in the chip and a demodulation part 46 demodulates respective symbols without using information on the idle chip position.
