چکیده
In the paper we have discussed the proposed water filling algorithm which has been used for allocating the power to the MIMO channels so as to enhance the capacity of the MIMO network. Here we present a theoretical framework for allocating the power here we have considered a 4x4 MIMO system the system is assumed to be MIMO-OFDM and the channel is assumed to be Flat as under this the convolution integral becomes a simple multiplication operator. Here is this paper we study the comparison of successive water filling algorithm with the proposed water filling algorithm with the change in the power budget. It can be observed from the graphs that the efficiency of the system is enhanced with the proposed water filling algorithm and also it is observed that the outage probability is reduced as compared to the outage observed in the successive water filling algorithms. It is further seen that there is enhancement in the capacity of a MIMO system. Keywords— Multi Input Multi Output (MIMO), water filling, Capacity, outage probability, Signal to Noise Ratio (SNR), Power Budget.Orthogonal Frequency Division Multiplexing(OFDM)

We analyze the ergodic capacity and channel outage probability for a composite MIMO channel model, which includes both fast fading and shadowing effects. The ergodic capacity and exact channel outage probability with space-time water-filling can be evaluated through numerical integrations, which can be further simplified by using approximated empirical eigenvalue and maximal eigenvalue distribu...
