This book will help you to clear your concept about MIMO technical system and how you will minimize the BER(bit error rate) and reduce the complexity and how you will improve the performance.In this book the proposed method does involve using MMSE (Minimum mean square error) to find out the beam weighted vector, hence future work can be done on power consumption using other method like Least Mean Squares (LMA) algorithm, Recursive least squares, Constant modulus algorithm methods or other methods of the same kind.So if anyone want to work in future with communication system then it will help...
