ABSTRACT:
A SINR estimator receiving a symbol stream has a delay element coupled to the symbol stream to produce a delayed symbol stream, which is also coupled to a conjugator. A first multiplier forms a product from the symbol stream and the output of the conjugator, thereafter summing these values over an interval L and scaling by L to form a correlated power estimate Cn. A second multiplier forms a product from the symbol stream which is multiplied by the conjugate of the input, thereafter summing these values over the preamble interval 2L and scaling by 2L to form a non-correlated power estimate Pn. Cn and Pn are compared to generate an SINR estimate.
