- An acceptable quality of the radio link is desired for nodes’ communication, which is obtained when the received power is larger than a threshold. SNR Estimation is a way to determine this acceptable quality of service. Many DF based algorithms rely on SNR estimation. For energy constrained radios, e.g. in WSNs, non-coherent demodulations may be required, which don’t require phast estimation and hence reduces the circuit consumption of energy.
- We have devised algorithms for the SNR Estimation in a non-coherent MFSK receiver using classical statistical signal processing approaches.
