应用背景This document describes how to set up a 6x6 multiple input, multiple output (MIMO) system using NI LabVIEW software and NI USRP™ (Universal Software Radio Peripheral) hardware. After a brief discussion of MIMO, the paper examines the hardware and software based on LabVIEW for a 6x6 MIMO-OFDM system using 4-QAM as modulation scheme. The system presented here is also capable of working as a 2x2 MIMO and 4x4 MIMO system with appropriate parameter configuration.关键技术With MIMO, you can increase wireless system performance without increasing power consumption. It is based on the idea that when using multiple antennas, the transmitted signal progresses through different wireless channels, from the transmitter antennas to the receive antennas, to

A simple example to verify the feasibility of applying compressed sensing for channel estimation. The pilot applies a PN pattern in the frequency domain. The density of pilot is less than the Nyquist sampling rate. Also it is assumed there are sparsity in the channel taps, which is the basis for applying compressed sensing.
