Microwave repeater station and communication method based on SCDMA microwave repeater station

Abstract

This invention provides a communicating method based on a SCDMA microwave repeater including: in a down link, a near-end computer picks up down-line signals of the subsystem of a transceiver of the SCDMA base station via a coupler, processes and transmits them to a far-end computer by microwaves, which receives the signals and recovers them to be emitted by a re-sending antenna, in an up link, a remote computer receives up signals sent by the re-sending antenna and processes then transmits them to the near-end computer by microwaves, which recovers the received up signals and then transmits them to the subsystem of the SCDMA base station transceiver.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a mobile communication repeater, in particular to a communication method based on an SCDMA microwave repeater and the microwave repeater. Background technique [0002] With the improvement of people's communication consumption level, people's demand for mobile communication is increasing day by day, and the requirements for mobile communication quality are getting higher and higher. This requires operators to improve the quality of mobile communication networks and expand coverage. How to improve the quality of the mobile communication network and expand the coverage has become an important issue for operators. [0003] Since the electromagnetic wave signal emitted by the mobile communication base station to the air will be affected by various objective factors such as terrain and buildings, it is impossible to cover every corner where the flow of people can reach, such as hig...

AI Technical Summary

Problems solved by technology

[0008] 1. The wireless receiving signal level requires high RXL≥-65dBm, and the signal quality SNR (Signal-to-Noise Ratio, signal-to-noise ratio) requires high requirements;

[0009] 2. Due to wireless reception, it is easy to introduce interference and the call quality is poor;

[0011] 4. Considering the isolation requirements of the system for sending and receiving, the site selection requirements are high, and the owner's coordination is difficult;

[0012] 5. The use of in-band frequency shift needs to occupy additional frequency and channel resources of the SCDMA base station system at the same time;

[0013] 6. The system is limited in sending and receiving. Generally, it is one receiving and one sending, and it cannot meet the requirements of the coverage area and adopt a flexible antenna coverage method;

[0014] 7. Due to the use of wireless reception, the overall SNR of the system is poor, and the effective coverage radius is small (that is, the call quality cannot be guaranteed when the signal is weak);

[0015] 8. A single networking method cannot achieve coverage of large areas in different areas
