Challenges in Future Short Range Wireless Systems

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, O...

Description
Summary: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
