I am using fast AGC in a TDD burst system.
The convergence time of the AGC is too slow for my signal which is an OFDM signal with GI of 128 (convergence takes about 250-300 samples). How can I make it much faster?
Another problem is that if I increase the signal power up to about -50dBm then the RSSI (probably due to the AGC) jumps suddenly up to about -35dBm and the signal gets disturbed in such a way that errors start on the link. What can be the problem?
