Abstract :
As RF and baseband engineers strive to satisfy the demand for ever higher data rates in next generation wireless systems, they are faced with three challenging requirements: both spectral efficiency and bandwidth have to be increased, and the cost per bit has to be kept low. A combination of MIMO, OFDM and TDD is a promising candidate technology to meet these objectives. However, realizing the potential gains of this approach requires tackling a number of new challenges: real MIMO channels, real-"Dirty"-RF and tough real-time constraints
