Problems solved by technology

However, the above method is relatively rough and cannot fully reflect the characteristics of smart antennas and the working conditions of smart antennas in the entire TD-SCDMA system
According to the above approximate processing method, it is impossible to accurately describe the smart antenna in the actual environment, let alone meet the precision requirements of the TD-SCDMA system simulation for the smart antenna, so that the simulation cannot obtain better results

Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0024] For the actual use of smart antennas, it is necessary to estimate the incoming wave direction of the access user first, and then change the pattern of the array antenna by adjusting the weighted amplitude and phase of each array element signal, so that the main lobe of the antenna pattern points to the access point. Incoming users, point the side lobe or null to the interference direction, that is, the smart antenna is adaptive. However, calculating weights based on user information to generate an antenna pattern is complex and time-consuming, and it is unnecessary in simulation. Therefore, the present invention uses a fixed-shaped antenna pattern to determine the antenna gain in each direction, and the antenna gain in each direction can be obtai...

Abstract

The invention discloses a realizing method for intelligent antenna in TD-SCDMA system stimulation. The method includes: divides the emitting region according to the type of intelligent antenna, and sets the direction of antenna in every region and records in data file; and decides the emitting region of accessing user according to angle direction of accessing user, and read the antenna direction of emitting region from data file, and calculates the power information of TD-SCDMA system. The method in invention models the intelligent antenna by the divided regions, and stimulates the intelligent antenna in TD-SCDMA system by antenna gain stimulation, so the stimulated results is accurate and dependable, and easy to be used, and fit for every intelligent antenna, and improve the stimulating efficiency and calculating speed.

Description

technical field [0001] The invention relates to smart antenna technology, in particular to a method for realizing a smart antenna in TD-SCDMA system simulation. Background technique [0002] Smart antenna is a space division multiple access technology, which is used to distinguish different users in space. In practical applications, the smart antenna is set at the serving base station and can form multiple narrow beams at the same time, each narrow beam is directed to a certain access user of the serving base station, and is adaptively controlled when the access user moves. Tracking, so as to establish a wireless link with relatively concentrated energy between the serving base station and the access user, so the smart antenna can effectively resist fading and interference, and can increase the system capacity. Based on the above advantages, smart antennas are widely used in TD-SCDMA systems. [0003] The working principle of the smart antenna is: use multiple high-gain na...
