Abstract
This paper develops a new dynamic-blind estimation of the combiner’s weight λ suggested for decode-and-forward cooperative based receivers and provides an empirical form for it. The estimation is performed by applying a monotonically decreasing formula on the incoming bit stream. The performance evaluation is investigated using the analytical probability of error (Pe) closed-form of the decode-and-forward cooperative transmissions. An adjacency is illustrated between the performances using the values of λ obtained by the proposed estimation against the use of optimum values of λ found by iterative search. A practical implementation of the decode-and-forward cooperative algorithm is also considered and the performance analysis is studied for different channel assignments. It is demonstrated that the proposed dynamic-blind estimation of λ provides in an overall performance on the verge of that of using optimum values of the combiner’s weight λ.
