Embodiment Construction

[0017] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] A configurable multi-frequency point short burst spread spectrum signal receiving device, including a down-conversion module, an AD sampling module, an acquisition module and a tracking module; wherein,

[0019] The short-burst RF signal first enters the down-conversion module, and the down-conversion module moves the frequency point of the short-burst RF signal from RF to intermediate frequency. For short-burst RF signals of different frequency points, the down-conversion module sets the frequency Vibration and filter parameters to move it to the required intermediate frequency range, the down-conversion module inputs the intermediate frequency signal to the AD sampling module, the AD sampling module digitizes the analog signal, and outputs the digital signal to the capture module and tracking module,...

Abstract

The invention discloses a configurable multi-frequency-point short burst spread spectrum signal receiving device, and belongs to the technical field of short burst spread spectrum signal receiving. The system comprises a parameter-configurable down-conversion module, a parameter-configurable capture module and a parameter-configurable tracking module, and achieves the receiving of short burst spread spectrum signals at different frequency points of a single channel through different parameter configurations. According to the invention, the signal receiving of a plurality of frequency points isrealized by utilizing one channel with configurable parameters, so that the short burst spread spectrum signal receiving processing of the plurality of frequency points can be realized by only needing the resource of one channel, and the problem of excessive resource occupation is effectively solved.

Description

technical field [0001] The invention relates to the technical field of receiving short burst spread spectrum signals, in particular to a configurable multi-frequency point short burst spread spectrum signal receiving device. Background technique [0002] The short-burst spread spectrum signal has "short-term" and "burst", and its duration ranges from tens of milliseconds to several seconds. Since the arrival time of the signal is uncertain, the continuous spread spectrum signal receiving technology is not suitable for short burst spread spectrum signals. A short burst spread spectrum signal usually consists of a sync segment, a tracking segment and a data segment. The synchronization segment is used for signal capture, the tracking segment is used for signal tracking and locking, and the data segment is used for transmitting information. Sometimes the tracking section does not exist, and at this time, it is necessary to complete the signal capture and tracking lock in the ...
