这个是关于TDOA的源程序，里面的文件，时间长了，也忘记都是干啥的，自己研究下借鉴(This is about the source of TDOA, inside the file, long time, and also forget are doing, their own research under the draw)

关于BPSK，QPSK，8QAM,16QAM，32QAM的调制解调程序。可作为单独模块加入到任何信道下，解调采用了两种方法。(On the BPSK, QPSK, 8QAM, 16QAM, 32QAM modulation demodulation process. As a separate module can be added to any channel, the demodulator uses two methods.)

In a multiple transmit antenna, single antenna per receiver downlink channel with limited channel state feedback, we consider the following question: given a constraint on the total system-wide feedback load, is it referable to get low-rate/coarse channel feedback from a large number of receivers or high-rate/high-quality feedback from a smaller number of receivers? Acquiring feedback from many receivers allows multi-user diversity to be exploited, while high-rate feedback allows for very precise selection of beamforming directions. We show that there is a strong preference for obtaining high-quality feedback, and that obtaining near-perfect channel information from as many receivers as possible provides a significantly larger sum rate than collecting a few feedback bits from a large number of users.
