IQ Derotated Meas (NB-IoT)
The IQ Meas trace. However, removes the additional rotation of each symbol, , leaving only the normal pi/x rotation (pi/2 BPSK Binary phase shift keying - A type of phase modulation using 2 distinct carrier phases to signal ones and zeros. or pi/4 QPSK Quadrature phase shift keying) and causing the constellation to look much cleaner. Refer to TS Technical Specification 36.211 section 10.1.6 for a description of how symbols are created. This trace is available only for uplink signals.
