In this study, we use 8PSK modulated PCMA signals as an example to study the performance of the proposed algorithm.
Figure 4 shows the PCC based on BPSK, QPSK, 8PSK, and 16QAM at different SNR.
(3) Assuring generality, constellations BPSK, QPSK, 8PSK, and 16QAM are assigned to each symbol in vector s, respectively.

To the most known PSK variations belong four-level QPSK and 8PSK techniques.
The graphs, Blue for BPSK, Red for QPSK Black for 8PSK and yellow for 16PSK modulation indicate BER average and green curve is the target BER.

"Support for the TD-SCDMA wireless standard significantly lowers the entry barrier and the design challenges baseband vendors are facing in targeting the subscriber base of China Mobile, the world's largest wireless operator, with more than 650 million subscribers." CEVA's TD-SCDMA software libraries support the latest TD-SCDMA technology compliant with the 3GPP Rel-9 worst case conditions and are user-configurable based on customer needs, including interleaver, rate matching, modulation type (8PSK, QPSK, 16QAM, 64QAM), HARQ, and more.
Additional features include header and payload compression as well as the support of 8PSK modulation in the inbound direction.
The major advantages of the GPRS technology were that it could provide data rates from 56 kbit/s up to 114 kbit/s, and data transfer through this technology was typically charged per megabyte of traffic transferred as against data communication via tradi-tional circuit switching which is billed per minute of connection time, independent of whether the user actually is utilising the capacity or is in an idle state.vbCrLFThe introduction of 8PSK encoding led to the evolution of GPRS networks to EDGE networks.
Also unveiled was the single-chip BCM7335 satellite SoC set-top box solution with PVR functionality that supports worldwide standards for direct broadcast satellite (DBS) set-top boxes based on DVB-S2, DVB-S and 8PSK, and is backward compatible with the DVB-S standards.
The Cartesian Feedback Loop (CFBL), first developed in the 1980s (1,2), is now well established as an option for highly efficient linear transmitters using modulation such as [pi]/4-DQPSK, 8PSK and QAM.
