Embodiment Construction

[0026] The device and method for adaptive channel estimation post-processing of the present invention will be described below in conjunction with the accompanying drawings.

[0027] see figure 1 , which is a block diagram of the apparatus for post-processing of adaptive channel estimation in the present invention.

[0028] The device for post-processing of adaptive channel estimation is set at the receiver end, which includes an original channel estimation value generation module 101 , a threshold value setting module 102 and a comparison and judgment module 103 . The original channel estimation value generation module 101 and the threshold value setting module 102 are respectively connected to the comparison and judgment module 103 .

[0029] The original channel estimation value generation module 101 is used to calculate and obtain the original channel estimation value h(n) by using the received pilot reference signal Y(k) and local pilot reference signal X(k).

Abstract

The invention discloses a self-adaptive signal channel estimation post treatment device and a method. The self-adaptive signal channel estimation post treatment device of the invention comprises an original signal channel estimation value generation module, a threshold value setting module and a comparison judgment module, wherein the original signal channel estimation value generation module uses received pilot frequency reference signals and local pilot frequency reference signals for calculation to obtain original signal channel estimation values, the threshold value setting module determines the signal channel post treatment threshold, the comparison judgment module sets all outside window pigtails of the original signal channel estimation values into zero, and remains the pigtail with the maximum pigtail power in all inside window pigtails of the original signal channel estimation values under the condition without multi-input and multi-output users through judging whether the multi-input and multi-output users exist or not under the condition that the pigtail powers of all inside window pigtails of the original signal channel estimation values are all smaller than the signalchannel post treatment threshold, and the remained pigtail with the maximum pigtail power is output as a signal. The users can be detected more effectively, and the precision and the performance of areceiving machine can be improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a device and method for post-processing of adaptive channel estimation in the field of mobile communication. Background technique [0002] With the integration of communication networks and data networks and the development of communication technologies such as Next Generation Network (NGN) and third generation digital communication (3rd Generation, 3G), receivers are widely used and popularized. In particular, after combining data services such as multimedia messaging, online games, video on demand, music downloads, and mobile TV, the receiver presents a large number of demands, greatly satisfying the needs of users. However, the wireless performance of the third generation digital communication (3rd Generation, 3G) network has indeed been greatly improved, but there are still limitations in meeting user requirements. [0003] During wireless communication, due to the very c...
