TDD digital radio communication system and method for operating the same

摘要

A TDD digital radio communication system includes a local oscillator for generating a local oscillation frequency being N times the transmission intermediate frequency and a frequency divider for dividing the local oscillation frequency by N. The frequency divider is enabled in the transmission mode to generate the transmission intermediate frequency and is disabled in the reception mode to completely stop generating the transmission intermediate frequency, so as to prevent interference with the reception intermediate frequency.
