Space-time adaptive processing (STAP) is an effective method for the clutter cancellation, but the computational complexity of the full degrees of freedom (DOF) is too large to achieve in practice. A modified dimension-reduced STAP method is proposed. By selecting auxiliary channels near the clutter ridge, this modified method is a suboptimum approach and it needs much less computational complexity...
This paper proposes a transmit power and bit allocation algorithm with constraint on allocated bit number. Transmit power and bit allocation algorithms help improve performance of OFDM systems, however the existing algorithms can't fully satisfy the need of baseband data modulation methods, which only map a certain number of input bits into a data symbol. The presented approach aims at maximization...
To cope with the deleterious channel fading effects on the system performance, diversity-enriched transmitters and receivers have well-appreciated merits. When the channel state information is available at the transmitter, precoders are designed to suppress the channel effect and enable the diversity and low-complexity receiver designs. In addition, the peak-to-average power ratio (PAR) issue has...
