A Practical System Model for the AFE of a Low-IF Receiver

The SL is the desired input signal of lowest amplitude for which the receiver can generate an output of "sufficient quality." Thus, the receiver noise floor should not be higher than SL - SNR^sub (min)^, with SNR(min) equal to the minimum required SNR for the given modulation and channel c...

Zusammenfassung:The SL is the desired input signal of lowest amplitude for which the receiver can generate an output of "sufficient quality." Thus, the receiver noise floor should not be higher than SL - SNR^sub (min)^, with SNR(min) equal to the minimum required SNR for the given modulation and channel coding system.
