Optimum Selection of Modes Set for Adaptive Modulation and Coding based on Imperfect Channel State Information
Mehrdad Taki , Reza Mahin Zaeem
Abstract:   (3080 Views)
Complexity issues and limited feedback rate strictly constrain the number of transmission modes in discrete link adaptation. A new algorithm is designed for selecting an optimum set of modes out of all the possible transmission modes based on the link’s characteristics and the constraints, meanwhile, imperfect channel state information (CSI) is available. The design goal is to maximize the average spectral efficiency and the selection is done using a combination of nonlinear quantization and integer programming. As numerical evaluations for adaptive LDPC or convolutional coded, QAM modulated transmission show, performance of the proposed scheme is considerably improved in comparison with the benchmark schemes.
Keywords: Link Adaptation, Adaptive Modulation and Coding, Integer programming
