1 shows the average SER versus SNR of the considered HSTRN, for infrequent light shadowing (satellite-relay LMS channel), with multiple values of CCI (-5 dB, 0 dB and 5dB) using different M-PSK modulation schemes: BPSK, QPSK and 8-PSK
The ERS calculates the PER of the measured signal using the four principal modulation schemes used in recent satellite communication technologies, namely, QPSK, 8-PSK
, 16-QAM, and 32-QAM.
The tailbiting codes search results for 4-PSK, 8-PSK
and 16-QAM modulation are presented in Section 4.
For equipment supporting 8-PSK
(EDGE GSM), the requirement for 8-PSK
modulation is -56 dB.
Illustrates our analytical results for 8-PSK
under Nakagami-m fading channel.

The solution exceeds all ETSI specification requirements and includes enhanced receiver sensitivity and the ability to receive and transmit 8-PSK
modulated signals for the E-GPRS air interface standard.
5 kbps) where the modulation scheme to be used is pulse-shaped (Gaussian) 3[Pi]/8 offset 8-PSK
as opposed to GSM (270.
The device can decode DVB/DSS QPSK and BPSK signals at 1-45 Msps, turbo QPSK at 15-30 Msps and turbo 8-PSK
signals from 15-30 Msps.
Benefits of the single chip Silicon Tuner are the reduced Bill-of-Material, reduced board space required due to small package size, suitability for 8-PSK
and QPSK modulation, as well as low power consumption (less than 0,8 W).
Tropian's TimeStar(TM) Multi-mode Polar Modulator (the TR15230N) -- targeted at E-GPRS, GAIT, and ANSI-136/AMPS applications -- is a CMOS integrated circuit that is capable of precisely generating GMSK, 8-PSK
, DQPSK, and FM modulation types using a conventional, non-linear (saturated-type) GSM power amplifier.
