Fig. 1From: Very-low-SNR cognitive receiver based on wavelet preprocessed signal patterns and neural networkThe block diagram of the PBCCS. The transmitter (a) PBCCS Transmitter Block diagram selects a 3-bit glossary space, so the corresponding “101” waveform is transmitted. The receiver (b) PBCCS Receiver Block diagram receives a distorted signal and produces the corresponding bitsBack to article page
