用BFGS算法求解无约束问题 是一种比秩1算法更有效的优化方法(Unconstrained problem with BFGS algorithm is an algorithm is more efficient than the rank of an optimization method)

提出了一个采用(2,1,7)卷积码+QPSK的中频调制解调方案,并在Xilinx公司的100万 门FPGA芯片上实现了该系统。该系统在信噪比SNR为6dB左右时可实现速率超过1Mbit/s、误码率 小于10-5的数据传输。 (Proposed a use of (2,1,7) convolutional code+ QPSK modulation and demodulation of the IF program, and in Xilinx' s FPGA chip one million on implementation of the system. The system SNR to 6dB signal to noise ratio at about the rate may achieve more than 1Mbit/s, less than 10-5 bit error rate of data transmission.)

说明：  该代码主要实现的功能是空时编码误码率，误码率随着信道的变化而变化(THE BER OF THE SPACE BASE CODE，the ber varied with the channel)
