Reply To: channel eistimation method

Dear Roaa,

For Approximate-Perfect method it is assumed that the channel is known and pilots are added to account for the overhead. The method PilotAided, on the other hand, uses the pilots to estimate the channel. Therefore, at low SNR (high channel estmation error) the throughput of the Approximate-Perfect scenario should be higher than the Pilot-Aided scenario and as the SNR increase (estimation error decreases) the thoughput gap between the two scenarios should decrease.

I hope this answers your question.
