To improve the performance of Peak-to-Average power ratio in Multi-input Multi-output Orthogonal frequency division multiplexing (MIMO-OFDM) systems and the spectral efficiency, a low-complexity blind cross-antenna successive shifting rotation and inversion (Blind-CASSRI) scheme is proposed. The algorithm based on the successive suboptimal CARI (SS-CARI) scheme increased the number of candidate sequences...
An integrated 6.2-9.5GHz CMOS UWB receiver for WiMedia MB-OFDM is proposed. The fully differential receiver consists of a wideband LNA and a down conversion mixer with high and low gain mode. A low-pass filter and a programmable gain amplifier are also included. The chip was fabricated in TSMC 0.13-μm RF CMOS process. Measurement results show that the receiver achieves voltage gain from 21dB to 63dB...
This paper presents a 1.2V CMOS RSSI based on successive detection structure. An equation estimating the maximum nonlinear error is derived and the simulation results show it is more accurate than the former one proposed by P. C. Huang. The RSSI achieves a wide bandwidth from 1MHz to 500MHz. The linear dynamic range is at least 80dB. The nonlinear error based on single frequency curve fitting is within...
