Abstract
Water filling algorithm can be used for mmWave (millimetre wave), MIMO (Multiple Input Multiple Output) systems. It offers channel optimality for AWGN and ISI (Additive White Gaussian Noise and Inter Symbol Interference) respectively. In this article we proposed the water filling algorithm for equal power allocation. In this we study the decomposition of MIMO wireless channel with the help of Singular Vector Decomposition (SVD). SVD is used for generating parallel channels and is a factorization of real and complex number. For optimality of MIMO power allocation constrained maximization problem occurs to solve this problem we use Lagrange multiplier. The performance of water filling algorithm may be approach the channel capacity. In this the result when SNR is high the suggested method with equal power allocation of water filling is studied.
