The license-free shaped-offset QPSK (SOQPSK) is interoperable with Feher-patented QPSK (FQPSK), in the sense that an integrate-and-dump offset QPSK detector produces the same output no matter which kind of transmitter is used.

phase noise. We start by developing coherent detectors for military standard SOQPSK (SOQPSK-MIL), which is full-response. For the partial response version used in aeronautical telemetry (SOQPSK-TG), the optimal detector requires a trellis of 512 states [8], we use a reduced-complexity option for SOQPSK-TGWhen offset quadrature phase-shift keying (OQPSK) is used in multiple input multiple output (MIMO) environment, orthogonal space-time block codes can be applied to waveforms to orthogonalize a space-time coded multiple-input, multiple output link. For offset QPSK, this technique has the advantage of eliminating the I/Q interference …Fig1. QPSK vs SQPSK modulator block diagram. As mentioned Quadrature Phase Shift Keying is referred as QPSK . Here maximum phase shift is limited to about 90 degree. In QPSK, first input bit stream is split into two bit streams referred as odd and even. These streams are applied simultaneously to the mixers.ARTM CPM, along with PCM/FM and SOQPSK-TG/FQPSK, is one of three modulation schemes standardized within IRIG-106 [1]. The legacy waveform, PCM/FM, is still widely used today though given the ongoing spectrum battles and increasing platform data rate requirements, the migration to SOQPSK/FQPSK has started. The more spectrally efficient SOQPSK/FQPSKdifferential encoder, an SOQPSK precoder, and a CPM modulator. Therefore, the transmission model is the same as in [9], except that the present CPM modulator has a shaped frequency pulse and thus outputs 1We emphasize that SOQPSK, like other CPMs, is a nonlinear modulation format. In the present context, the word shaped refers to the

These spacings in normal-ized frequency are independent of the coderate and constellation used, however the actual spacingOffset QPSK, which involves adding a delay to one of two digital data streams used in the modulation process, reduces the maximum phase jump to 90°. Another option is π/4-QPSK, which reduces the maximum phase jump to 135°.
