Search for: [Description = "Orthogonal frequency division multiplexing \(OFDM\) provides better spectral efficiency than frequency division multiplexing \(FDM\), while maintaining orthogonal relation between carriers\; hence traffic is better carried by OFDM than FDM within the same spectrum. This paper reveals a comparison of spectral efficiency, performance of communication system in context of bit error rate \(BER\) for the same information rate and peak to average power ratio \(PAPR\) of quadrature amplitude shift keying \(QPSK\) and 16\-quadrature amplitude modulation \(16\-QAM\) technique."]
