Abstract

We propose an elegant source coding technique with highly asymmetric frequencies of occurrences of different symbols. Keeping the symbol with the highest frequency of occurrence as silent during transmission, we achieve substantial savings of transmitter and receiver energies by using a hybrid Amplitude Shift Keying (ASK) - Frequency Shift Keying (FSK) modulation/ demodulation technique. Our results show that for channels with Additive White Gaussian Noise (AWGN), on an average, the transmitter side energy is reduced by about 53%, while at the receiver side there is about 17.2% savings. Due to the savings of transmitter and receiver energies and the low cost/complexity of the proposed transceiver, our proposed scheme is suitable for multi-hop communication in Cognitive Radio Networks (CRNs).
