Abstract
In this research we present an introductory analysis of a complex aspect of mobile communications. Doppler effect is evaluated in both Ricean and Rayleigh fading channels. A non-coherent 2-FSK scheme is selected to evaluate the behavior of the system under very strong fading channel conditions. The analysis is conducted for the binary case due to the possibility of developing closed form solutions. Therefore, the approach is simplified avoiding long lasting simulations that may obscure the concepts. The probability of bit error for the 2-FSK case can also be used as an initial bound for a M-FSK scheme. Diversity is evaluated as a means of combating fading and Doppler effects. Error correcting codes, in the form of convolutional algorithms, are also used and applied to both effects.
