Title:
METHOD FOR CALCULATING SIGNAL TO NOISE RATIO AND USER EQUIPMENT (UE)
Document Type and Number:
WIPO Patent Application WO/2017/101104
Kind Code:
A1
Abstract:
Disclosed are a method for calculating a signal to noise ratio and a user equipment (UE), capable of saving storage resources and improving calculation rate. The method in the embodiments of the present invention comprises: acquiring a pilot signal; calculating a channel coefficient value corresponding to the pilot signal; calculating a first signal to noise ratio (SNR) of each sub-carrier of a target data stream according to a current signal to noise ratio, the channel coefficient value and a related parameter of a linear receiver, and calculating a second SNR of each sub-carrier under ideal interference elimination; calculating a first average received bit information rate (RBIR) of the sub-carrier of the target data stream according to the first SNR, and calculating a second average RBIR of the sub-carrier of the target data stream according to the second SNR; calculating a third average RBIR of a maximum likelihood receiver according to the first average RBIR, the second average RBIR, a first interpolation coefficient and a second interpolation coefficient, wherein the first interpolation coefficient is related to a modulation order, and the second interpolation coefficient is related to encoding efficiency; and mapping the third average RBIR to be a third SNR.
