High Resolution 3-D Angle of Arrival Determination for Indoor UWB Multipath Propagation
Propagation measurements using a large array are used to study the angle of arrival (AOA) across the ultrawideband (UWB) frequency range of 3.1 to 10.6 GHz. A two-dimensional Unita...

A Post-Detection SNR-Aided Timing Recovery Loop for MIMO-OFDM Receivers
--- In this paper, a novel third-order Phase Lock Loop (PLL) is proposed for the timing recovery in MIMO-OFDM systems. It differentiates from conventional timing recovery algorithm...
