Weband Offset QPSK use two points-per-symbol (symbols and midpoints between symbols) to compute EVM and peak EVM due to the offset between I and Q. For Offset QPSK , when the Half Sine Filter is selected, the OQPSK reference constellation points fall on a circle with a magnitude of sqrt(2)/2, but the EVM is still expressed as a percentage of the … Webt. e. Single-carrier FDMA ( SC-FDMA) is a frequency-division multiple access scheme. It is also called linearly precoded OFDMA ( LP-OFDMA ). Like other multiple access …
