Abstract

The invention discloses a high-quality and fast-frequency-hopping TDD wireless transceiving system. The system comprises a baseband signal processing module, a first frequency synthesis module and a second frequency synthesis module; the transmitting end and the output end of the baseband signal processing module are connected to a transmitting circuit frequency mixer and a receiving circuit frequency mixer respectively; a first radio-frequency switch is arranged between the first frequency synthesis module and the second frequency synthesis module; and the input selection end of the first radio-frequency switch is electrically connected with the first frequency synthesis module and the second frequency synthesis module. The invention relates to the technical field of wireless communication systems, in particular to the high-quality and fast-frequency-hopping TDD wireless transceiving system. While one frequency synthesizer module works, the other frequency synthesizer module can enteranother frequency point working state in advance, and when ready, a path is switched by controlling the radio-frequency switch, thereby achieving the purposes of quickly switching a frequency and stably outputting a local oscillator signal.

Description

technical field

[0001] The invention relates to the technical field of wireless communication systems, in particular to a high-quality, fast frequency-hopping TDD wireless transceiver system. Background technique

[0002] Frequency hopping communication is a kind of spread spectrum communication, which is mainly used in military communication, such as tactical frequency hopping radio, anti-jamming, etc., and is rapidly penetrating into civil communication, such as mobile communication, data transmission, wireless local area network.

[0003] Frequency hopping is to use the spread spectrum code sequence to carry out frequency shift keying modulation, so that the carrier frequency continuously hops. Frequency hopping communication has anti-jamming and anti-interception capabilities, and can share frequency resources. Using the fast hopping of the carrier frequency, it has the function of frequency diversity, so that the system has the ability to resist multipath fading. The ...
