Abstract :
The potential of an SNR estimation technique for use in links subject to multipath propagation and periodic shadowing is investigated. The proposed SNR estimator relies on the bit error rate of un-coded pilot sequences. The estimator´s performance in the presence of Ricean fading, periodic shadowing and rain attenuation is analyzed by means of simulations. The proposed technique is shown to provide good estimation performance with reduced complexity compared to existing techniques.
