Nov 10, 2011 Β· The capacity of SOQPSK-TG. Abstract: In this paper we compute the capacity and the pragmatic capacity of aeronautical telemetry shaped-offset quadrature phase-shift keying (SOQPSK-TG). In the pragmatic approach, SOQPSK-TG is treated as a modulation scheme as opposed to an encoder, and no iterations are performed between the SOQPSK-TG ... E-SOQPSK is an OFDM structured single carrier modulation waveform, configurable to include OQPSK, SOQPSK, or mQAM. Preliminary laboratory results confirmed its ...

Identifiers . book ISBN : 978-1-4244-2970-7 ...Symbol rate. In a digitally modulated signal or a line code, symbol rate, modulation rate or baud rate is the number of symbol changes, waveform changes, or signaling events across the transmission medium per unit of time. The symbol rate is measured in baud (Bd) or symbols per second. In the case of a line code, the symbol rate is the pulse ...methods (FQPSK-B, FQPSK-JR, and SOQPSK-TG) are interoperable and require the use of the differential encoder described in . Chapter 2, Paragraph 2.4.3.1.1. Additional information on this differential encoder is contained in Appendix M. All of these bandwidth-efficient modulation methods require the data to be randomized. 2.3 Other Notations
