Modified SNR Gap Approximation for Resource Allocation in LDPC-Coded Multicarrier Systems

IEEE Access, 2020
The signal-to-noise ratio (SNR) gap approximation provides a closed-form expression for the SNR required for a coded modulation system to achieve a given target error performance for a given constellation size. This approximation has been widely used for
