Embodiment 1

[0046] like Figure 4 As shown, the present embodiment adopts two alternative phase detection schemes: the phase detection module 1 adopts a relatively low computational complexity, but its performance is general, and the main parameter affecting its computational complexity and performance is the number of multipaths; the phase detection module 2 Using the scheme given by the aforementioned physical layer protocol, the performance is better, but the computational complexity is high. The main parameter affecting its computational complexity and performance is the number of multipaths, and its performance is also affected by the prior feedback error probability information. Impact.

[0047] The adaptive control unit acquires wireless channel quality information Q, where the wireless channel quality information includes but is not limited to received signal to noise and interference power ratio (SNIR), received bit error rate (BER) or block error rate (BLER), At the same time, ...

Abstract

The present invention provides an adaptive phase detection method. The method includes the following steps that: adaptive control is carried out according to wireless channel quality information, so that parameter configuration of phase detection is obtained; phase detection is carried out according to the parameter configuration, and phase detection results are outputted; and an effective phase detection result is selected and outputted. According to the adaptive phase detection provided by the invention, an adaptive phase detection scheme which is low in computational complexity and has performance that satisfies requirements is selected; according to the wireless channel quality information, phase detection calculation is further simplified, or the parameter configuration of phase detection performance is improved; and therefore, the computational complexity and performance of the phase detection can be adaptively adjusted according to the change of wireless anycast environment.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an adaptive phase detection method and system. Background technique [0002] In the mobile communication system, the wireless signal propagation environment is very complex. The signal transmitted by the base station antenna will be divided into multiple paths to reach the destination at different times, and each path has different effects on the amplitude and phase of the signal. Therefore, these independent or highly uncorrelated multiple signals can be used to improve the performance of wireless links. Diversity technology is a technology that uses multiple signals to improve the performance of wireless links. Two or more antennas are used in the base station to transmit signals to the mobile receiver, and the receiver receives the same signal from different transmitting antennas. Different versions of different versions, after combined processing, can significantly im...
