Comparison of Different Modulation Schemes for Signal Decoding in Analog Network Coding
This paper discusses different modulation schemes for the decoding of signals in Analog Network Coding (ANC). Analog Network Coding is a concept in which interference of the signals is considered as advantage rather than disadvantage. Router interferes the signal transmitted from two nodes that want communication between them. At the receiving end the node subtracts its own signal to decode the signal transmitted by the sender. Signal decoding at the receiving end is not a simple problem. Signal has to traverse through the channel to reach the receiver. Channel imparts many distortions in the signal in the form of magnitude and phase.
