Because of the current set up the distance between the two SDRs were only about \si{2}-\SI{3}{\meter}. The signal were sent with a gain value of 0.4. The phase change and amplitude changes could be seen well. Specially when the transmitter or the receiver were moved, the change of them get faster. -The BER which will be described in detail in the next section was on average 2.37 for the outdoor environment and for the indoor about 2.67. It makes sense that the fading effect occurs more in an indoor environment, because there were more possibility for reflections at this distance as in the outdoor environment. +The BER, which will be described in detail in the next section, was on average 2.37 for the outdoor environment and for the indoor about 2.67.

This is done with the help of a user specified \(k\)-byte test frame in the beginning of each vector. As seen in listing \ref{lst:ber-work}. Every bit is compared with the test vector at the beginning before the modulation and demodulation part. @@ -465,11 +463,11 @@ Unfortunately the two SDR need an external clock generator.
