Figure 16From: Collaborative reception technique in wireless sensor networks using adaptive antennasThe BER results for the 4-QAM with 2 and 4 nodes (antennas). Performance curve of BER as a function of Eb/N0 for a collaborative array with 2 and 4 nodes (antennas), functioning with a 4-QAM system in a multipath channel (see Equation 30) and AWGN.Back to article page
