Embodiment 1
[0066] (1) Given the user ADC quantization bit number b, the loss coefficient is calculated by the following formula:
[0067]
[0068] (2) Calculate the coefficient from the number of base station antennas N, the pilot length τ and the coherent time interval T as follows;
[0069]
[0070] (3) by e q , η, and SNR γ 0 , to calculate the optimal user antenna ratio as follows
[0071]
[0072] Then the number of optimal user scheduling is M opt =Nβ opt .
