In this paper, propagation channel measurement data obtained by using the wide-band multiple-input-multiple-output (MIMO) channel sounder — PROPsound — is applied to analyzing the cross-correlation behavior of spatial-polarimetric (SP) channels in indoor environments. Four antennas are selected from the transmitter (Tx) array and from the receiver (Rx) array to form a 2×2 spatial MIMO channel, with...
A successive approximation register analog-to-digital converter(SAR ADC) targeted for use in RSSI(received signal strength indicator) is presented. The measured signal-to-noise-and-distortion ratios(SNDR) of the ADC is 53.95 dB at 1MS/s sampling rate with power consumption of 147.6 μW from 1.2-V supply voltage, thus the resulting FOM is 0.437 pJ/conversion-step. The ADC is fabricated in a 0.13-μm...
