Embodiment Construction

[0040] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0041] In order to solve the channel estimation problem when the air interface propagation delay is large in the network hard simulation system, and avoid the interference of the signal transmitted by the simulated transmitting terminal on other time slots. The present invention is based on the standard frame structure of Time Division Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access), and adopts a new general frame structure of a TD-SCDMA hard emulation system, such as image 3 As shown, the general frame structure is composed of a data (DATA) part, a training sequence (MA, Midamble) part and a guard interval (GP, Guard Period) part. Among them, the DATA part is used to carry business data, and its length is a chip; the MA part is used for channel estimatio...

Abstract

The invention discloses a method for processing signals based on frame structure extension. The method comprises the steps as follows: a simulated transmission terminal sends uplink signals to base stations according to the universal frame structure or optimized frame structure of a network emulsion system; and the base stations process the signals according to the universal frame structures or optimized frame structures of the uplink signals. The invention also discloses a system for processing signals based on frame structure extension. By using the method and the system, the problem of channel estimation in case of long air interface propagation delay is solved; and the signals can be prevented from interfering with other time slots after being transmitted by the simulated transmission terminal, and can keep consistent with the standard frame structures to the greatest extent at the same time.

Description

technical field [0001] The invention relates to a time division duplex mobile communication system, in particular to a signal processing method and system based on frame structure extension. Background technique [0002] Whether it is the second generation or the third generation mobile communication system, it is finally embodied in the form of a mobile communication network, and network optimization is an important part of the mobile communication network. Usually, network optimization relies on test terminals, that is, through test terminals to generate and record relevant data in the coverage area of ​​the mobile communication system, and then optimize the network through data analysis. However, the signal processing capability and accuracy of the test terminal are limited, and at the same time it needs to rely on the existing configuration of adjacent cells. In actual situations, the missing configuration of adjacent cells is common. Therefore, the method of using test ...
