FIGURE 8.3 Relay-aided c ooperative transmission in wireless networks.
• Bandwidth
W =3.5 MHz.
•SNR
min
=2.3 dB. This corresponds to a rate of 5 Mbps.
• Packet size
a= 8000 bits.
• Path-loss exponent α=3.0.
• Slot duration T =3.2 ms.
We consider the following two simulation scenarios.
8.3.1 Path Loss Plus Rayleigh Fading
In this scenario, the path-loss factor and the fast Rayleigh fading contribute
to the channel gain, that is,
