Figure 4
The two graphs are labelled a and b, showing system throughput in bits per second per hertz on the vertical axis from zero to two, and signal-to-noise ratio in decibels on the horizontal axis from zero to thirty-five. Each plot includes curves for Proposed, Proposed Simulation, EH C N O M A S T B C, C N O M A S T B C, and EH C N O M A with I equal to one. Throughput increases with increasing signal-to-noise ratio, starting near zero at low values and approaching approximately two bits per second per hertz at higher values. All curves exhibit a monotonic increasing trend across the signal-to-noise ratio range in both subfigures.System throughput versus SNR
