There is D-Link AP(commercial AP) as the  transmitting device which has two antennas and Desktop computer with intel 5300 wireless card as receiving device which has three antennas. \r\nWhen processing the CSI with matlab, the CSI plot for one channel which transmits about 100 packets looks like this.\r\n![ss](https://cloud.githubusercontent.com/assets/13158999/8519080/7bcd136e-2402-11e5-8992-5bf8337bfc2c.png)\r\nI did the test in a typical office room. There isn’t any movement or change in the room and I get about 100 packets. This figure just describes one link about csi(1,1,:) at extended period, I can’t understand why there are two kinds of waveforms in one channel and there is stable waveform in theory.
