对于贝尔实验室提出分层空时码中的垂直结构进行仿真。(For the Bell Labs layered space-time codes proposed in the vertical structure of the simulation)

Considered a 16QAM communication system. The information rate is 2 Mb/s and the carrier frequency is 12 GHz. Assumed perfect synchronization. a) Simulated the system if the channel is AWGN and draw bit error rate of the system versus Eb/No. Compare the results with what you obtain in theory. b) Considered (15,11) Hamming code. Apply this code into the above system. Compare the results with what you obtain in theory. c) Simulated uncoded system if we have a Doppler Spread due to mobile movement in the channel. Simulate and draw the bit error rate of the system for maximum mobile speed 42.3 Km/Hour. No equalizer is used in the system. d) Applied coding of part (b) into the system of part (c). Simulate the system and discuss the results. e) Designed an interleaver for the system of part (d) to improve the coded performance results. Simulated the system.

潮流计算是电力学名词，指在给定电力系统网络拓扑、元件参数和发电、负荷参量条件下，计算有功功率、无功功率及电压在电力网中的分布。潮流计算是根据给定的电网结构、参数和发电机、负荷等元件的运行条件，确定电力系统各部分稳态运行状态参数的计算。通常给定的运行条件有系统中各电源和负荷点的功率、枢纽点电压、平衡点的电压和相位角。待求的运行状态参量包括电网各母线节点的电压幅值和相角，以及各支路的功率分布、网络的功率损耗等。(Power flow calculation is a term of power science. It refers to the calculation of the distribution of active power, reactive power and voltage in power network under given network topology, component parameters and generation and load parameters. Power flow calculation is based on the given grid structure, parameters and operation conditions of generator, load and other components to determine the steady-state operation parameters of each part of the power system. Usually, the given operating conditions include the power of each power source and load point, junction voltage, balance point voltage and phase angle. The parameters to be determined include the voltage amplitude and phase angle of each bus node, the power distribution of each branch and the power loss of the network.)
