Performance analysis of group-blind multiuser detector with blind channel estimation

We describe an approach to the performance analysis of the recently developed group-blind multiuser detector with known channels and blindly estimated channels. Specifically, we get the asymptotic distribution of the estimated group-blind detectors with known channels, and numerical ground to obtain an analytical Hermitian matrix with the blindly estimated channels. These make it possible to express the signal to interference plus noise ratio (SINR) analytically. Analytical results obtained in this paper match very well with the simulation results.
