Heterogeneous networks have been developed to improve spectral efficiency of cellular wireless networks. Interference among heterogeneous networks decrease the spectral effeciency. In this paper, we propose a partial interference alignment in heterogeneous networks which requires only partial channel knowledge and simple computation. The proposed scheme(More)
Various channel estimation methods have been proposed for shallow underwater communication channel with sparse channel type. A matching pursuit (MP), which is one of typical sparse channel estimation methods, can detect dominant components of sparse channel sequentially as a portion of matching. Mean squared error of MP, however, converges to fixed value(More)
