Table 1 Five kinds of fading channels

From: FPGA implemented testbed in 8-by-8 and 2-by-2 OFDM–MIMO channel estimation and design of baseband transceiver

Channel index Average power model Average power proportion Total of received power
1 Flat 1 1
2 Equal 1:1:1 1
3 Halfly decayed 1:0.5:0.25 1
4 Exponentially decayed \(1{:}e^{{ - \beta_{0} }}{:}e^{{ - 2\beta_{0} }}\) 1
5 Exponentially decayed \(1{:}e^{{ - \beta_{0} }}{:}e^{{ - 2\beta_{0} }}\) 2
