The AWGN Channel Block in the Communications Blockset lets you specify SNR in several ways, including Eb/No. Sometimes people want to use a more itemized way of specifying the SNR, like the itemization found in a link budget.
These two models show how to create equivalent implementations of a communication channel, one using the AWGN Channel block and the other using specifications for Transmitter Gain, Antenna Gain, Path Loss, and Receiver Noise Temperature.
explain more in better manner...............so a student can understand without using his much mind
