SINR derivations for the MMSE case in [5] are done only for low SNR region. In both [3] and [5], channel estimation error variance is assumed to be constant for all SNRs. This is not.

Different kinds of channel state information. (also known as the minimum-variance unbiased. MMSE estimation can both decrease the estimation error and shorten.

Mitigating Channel Estimation Error with Timing Synchronization Tradeofi in Cooperative Communications. of channel estimation error variance,

different components of channel-estimation errors, we develop a simplified model which separates the estimation errors of a. Wiener-filtered received signal into the amplitude error and the phase error. Based on the model, we derive tight bounds on component error variances. Moreover, we prove that the classical.

The results were produced within +/- 5% error margin which means the results.

SNR on the throughput of a broadcast channel. We pro- pose a generalization of the opportunistic transmission in which the transmitter still sends to the user with the high- est estimated SNR, but backs off on the transmit rate based on the variance of the estimation error. We obtain the op- timum amount of back off and.
