Digital electronics is one of the fundamental courses found in all electrical engineering and most science programs. The great variety of LabVIEW Boolean and numeric controls/indicators, together with the wealth of programming structures and functions, make LabVIEW an excellent tool to visualize and demonstrate many of the fundamental concepts of digital electronics. The inherent modularity of LabVIEW is exploited in the same way that complex digital integrated circuits are built from circuits of less complexity, which in turn are built from fundamental gates. This manual is designed as a teaching resource to be used in the classroom as demonstrations, in tutorial sessions as collaborative studies, or in the laboratory as interactive exercises.

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

We investigate the case of independent Rayleigh faded paths between antenna elements and find that with high probability extraordinary capacity is available. Compared to the baseline n = 1 case, which by Shannon’s classical formula scales as one more bit/cycle for every 3 dB of signaltonoise ratio (SNR) increase, remarkably withMEAs, the scaling is almost like n more bits/cycle for each 3 dB increase in SNR. To illustrate how great this capacity is, even for small n, take the cases n = 2, 4 and 16 at an average received SNR of 21 dB. For over 99 of the channels the capacity is about 7, 19 and 88 bits/cycle respectively, while if n = 1 there is only about 1.2 bit/cycle at the 99 level. For say a symbol rate equal to the channel bandwith, since it is the bits/symbol/dimension that is relevant for signal constellations, these higher capacities are not unreasonable. The 19 bits/cycle for n = 4 amounts to 4.75 bits/symbol/dimension while 88 bits/cycle for n = 16 amounts t
