Embodiment Construction
[0045] like figure 1 As shown, the methods to improve the measurement accuracy of signal-to-noise ratio include:
[0046] For the M code channels corresponding to a resource block, calculate the signal power of N user code channels, the signal power of N pseudo user code channels corresponding to the user code channels, and remove the N user code channels and the N The idle code channel average power of the M-2N idle code channels of a false user code channel;
[0047] When judging that the signal power of the pseudo-user code channel satisfies the power leakage compensation condition, compensate the signal power of the user code channel corresponding to the pseudo-user code channel with the signal power of the pseudo-user code channel;
[0048]Calculate the non-user code channel average power of M-N code channels other than the N user code channels, and calculate the signal-to-noise ratio of each user channel according to the non-user code channel average power;
