Dear members of the wireless research community, please guide me.
In the image of an equation given below, N is the antennas at BS and K is the UTs; eta is the ratio of length of pilot to data symbols; mu is the ratio of pilot symbol energy to data symbol energy; alpha is the fading second moment; rho denotes the channel's imperfect estimation; and the mean SNIR for the ZF detector is given as gamma. What pertinent information can we glean from the equation? Secondly, how can we draw some useful asymptotes from this equation? because standard BER commands are typically used in Matlab simulations, and these equations are not simulated for BER. Secondly, if in the equation we change the parameter (N-K+1) to N (which is the case for MRC), what insights do we get from that?
The average SNIR (signal-to-noise-and-interference ratio) of a massive MIMO detector can be used to determine the performance of the detector when the channel state information is imperfect. This information can be used to evaluate the effectiveness of the detector in a given communication system and to identify potential ways to improve its performance. Additionally, the average SNIR can provide insight into the level of interference present in the system, as well as the overall signal quality. This information can be useful in determining the best strategies for mitigating interference and improving communication performance.
Muinuddin Bashar Aronno, Thank you for your response. Yes, I am aware of that. Actually, I'd like to know about the equation (attached as an image). For example, what information do we gain if we change the parameter (N-K+1) in the equation (for ZF) to N (for MRC)? Second, how can we draw the asymptote from the equation when standard BER vs. SNIR commands are typically used in MATLAB simulations even for BER calculations with imperfect channel state information and equations (such as the one in the image for an imperfect channel) are not simulated for BER?
