An optimum hardware detector for constant envelope quadrature-quadrature phase-shift keying (CEQ2PSK)

چکیده
A hardware detector for constant envelope quadrature-quadrature phase-shift keying (CEQPSK) is proposed. It uses appropriate hard decisions; yet, it achieves optimum probability of bit error performance, unlike the suboptimum detector of Saha and Birdsall. This optimum performance is verified through Monte Carlo computer simulations. Additionally, a more correct expression is given for the probability of bit error performance for CEQPSK, which gives the gain over nonconstant QPSK as 1.44 dB, rather than the previously published value of 1.76 dB.

De Los Santos et al., Radio Systems Engineering, DOI 10.1007/978-3-319-07326-2_2, © The Authors 2015 Abstract In this chapter, we present a number of topics surrounding modulation and demodulation. We begin by introducing system-level block diagrams of AM and FM/PM modulators and demodulators, and explaining their respective principles of operation. In particular, under the topic of AM Mo...
متن کاملVisualization of 4D Q2PSK and CEQ2PSK in ideal bandlimited channels
This paper presents new visualization techniques for 4D Quadrature-Quadrature Phase Shift Keying (QPSK), Saha’s Constant Envelope (CE) QPSK, and Cartwright’s CEQPSK in ideal bandlimited channels. The signal diagrams analyzed are: time-signal eye patterns for 4D passband signals, 2D complex trajectory diagrams of baseband signals, and time-signal eye patterns for the 1D outputs of the baseband m...
متن کاملA Novel Expanded 16-Dimensional Constant Envelope QPSK Constellation
We introduce a 16-dimensional constant-amplitude constellation that is generated by concatenating either four constant envelope quadrature-quadrature phase shift keying (CEQPSK) symbols from Saha and Birdsall or four CEQPSK symbols recently discovered by Cartwright and also introduced here. Our new constellation doubles the number of points available for data transmission without decreasing the...
متن کاملA Cross-Correlated Trellis-Coded Quadrature Modulation Representation of MIL-STD Shaped Offset Quadrature Phase-Shift Keying
We show that MIL-STD shaped offset quadrature phase-shift keying (SOQPSK), a highly bandwidth-efficient constant-envelope modulation, can be represented in the form of a cross-correlated trellis-coded quadrature modulation, a generic structure containing both memory and cross-correlation between the in-phase and quadrature-phase channels. Such a representation allows identification of the optim...
