Conventional QPSK has 180° phase transitions and hence it requires linear amplifiers with high Q factor. The phase transitions of Offset-QPSK are limited to 90° (the 180° phase transitions are eliminated)SOQPSK-TG has a4 state trellis [15] with small decoding complexity. SOQPSK-TG uses a precoder [16] to convert binary information to ternary symbols which are modulated using a CPM modulator with a modulation index h = 1/2. The precoder imposes OQPSK-like properties on SOQPSK-TG while a constant envelope results from the CPM mod-ulator.To provide a better shopping experience, our website uses cookies.
