Power Allocation Techniques in MIMO Systems

چکیده
Bitand power allocation techniques for Multiple-Input Multiple-Output (MIMO) systems are investigated for minimizing the overall bit-error rate (BER) at a fixed data rate. In this work optimal power allocation (PA) technique based on the Lagrange multiplier method is studied and compared with suboptimal solutions. Our results obtained by computer simulations show that power allocation works very well in combination with an appropriate number of activated MIMO.

Power Allocation Strategies for MIMO Radar Waveform Design
The role of waveform design is central to effective radar resource management for state-of-the art radar systems. The waveform shape employed by any radar system has always been a key factor in determining the performance and application. The design of radar waveform to minimize mean square error (MSE) in estimating the target impulse response is based on power allocation using waterfilling. ...

متن کاملTransmit Beamforming for MIMO Communication Systems with Low Precision ADC at the Receiver
Multiple antenna systems have been extensively used by standards designing multi-gigabit communication systems operating in bandwidth of several GHz. In this paper, we study the use of transmitter (Tx) beamforming techniques to improve the performance of a MIMO system with a low precision ADC. We motivate an approach to use eigenmode transmit beamforming (which imposes a diagonal structure in t...
