A variable-precision distributed arithmetic (VPDA) multi-input multi-output (MIMO) equalizer is presented to reduce the size and dynamic power of 112 Gbps dual-polarization quadrature phase-shift-keying (DP-QPSK) coherent optical communication receivers. The VPDA MIMO equalizer compensates for channel dispersion as well as various non-idealities of a time-interleaved successive approximation register (SAR) based analog-to-digital converter (ADC) simultaneously by using a least mean square (LMS) algorithm. As a result, area-hungry analog domain calibration circuits are not required. In addition, the VPDA MIMO equalizer achieves 45% dynamic power reduction over conventional finite impulse response (FIR) equalizers by utilizing the minimum required resolution for the equalization of each dispersed symbol.
摘要:
An efficient method for the extraction of hemodynamic responses in Near-Infrared Spectroscopy (NIRS) systems is proposed to increase the spatial and temporal resolution without hardware overhead. The performance improvement is attributed to high Signal-to-Noise-Ratio (SNR) receivers, a modulation scheme, and a Multi-Input-Multi-Output (MIMO) based data extraction algorithm. The proposed system shows an over 2× increment in the figure of merit (FOM) compared to conventional designs. Experimental results support the validity of the proposed system.
