WebJan 12, 2024 · OQPSK RRC Spectral efficiency Download conference paper PDF 1 Introduction In case of the channels with constant parameters and additive noise the values of spectral efficiency above 2 bps/Hz can be achieved due to application of signals based on Faster-than-Nyquist (FTN) pulses. WebRefer QPSK modulation>>, OQPSK & π/4QPSK>>, DQPSK>>, SQPSK>> and BPSK vs QPSK>> for more information. Benefits or advantages of QPSK. Following are the benefits or advantages of QPSK: In QPSK modulation, two bit are carried by one single analog carrier. Hence bandwidth is twice efficient in comparison to BPSK modulation.
