calculate catalan number

基于单芯电缆的多载波技术，FPGA,OFDM通信程序，调制解调器，调制模块(Multi-carrier technology based on the single-core cables, the FPGA, the OFDM communication program, the modem modulation module)

上位机与三菱PLC之间进行TCP/IP通讯(communication between PC and PLC)

First, when the inter-user distance d is small, the SNR for D2D communication is high, and hence there are sufficient number of bits for high quality CSI exchange.

说明：  不同信噪比下，能量检测虚警概率与检测成功率的关系(The relationship between energy detection false alarm probability and detection success rate under different SNR. .)

本程序为CDMA系统中基于MMSE的多用户检测技术，供有相关人士下载(This procedure for the CDMA system based on the MMSE multi-user detection techniques for those who have related downloads)

分析瑞利衰落信道下qpsk的snr与ber的关系(The relationship between QPSK SNR and ber in Rayleigh fading channel is analyzed)

说明：  该软件的处理类似于短时傅立叶变换（STFT），但应用了更长、更重叠的分析/合成窗口，使时频处理从根本上对混叠具有鲁棒性。这种差异与非常活跃的时频处理技术有关，例如Dirac或优化的自适应波束形成器。(The software does processing similar to the short-time Fourier transform , but applies the longer and more overlapping analysis/synthesis window to make the time-frequency processing fundamentally robust for aliasing.)

这是在uwb系统中，用TOA定位法的的整个系统的仿真程序源码 (This is a simulation program source code for the entire system in uwb systems, TOA positioning method)

16QAM数字基带信号系统仿真，包括发射机程序和接收端程序(16QAM digital baseband signal system simulation)
