Signaling constellations for fading channels
TL;DR: New expressions for the exact symbol error rates (SER) in fading with diversity combining are derived for any two-dimensional signaling format having polygonal decision boundaries and make it possible for the first time to optimize parameters of various constellations precisely and to determine, which constellation has the lowest probability of error.
Journal ArticleDOI
PSK and DPSK trellis codes for fast fading, shadowed mobile satellite communication channels
TL;DR: The performance of 8-PSK and 8-DPSK trellis codes is presented for a class of fast fading, land mobile satellite communication channels and optimality is found to be dependent on the presence of lognormal shadowing.
Journal ArticleDOI
Error probabilities of two-dimensional M-ary signaling in fading
TL;DR: A new exact method for computing the average symbol error probability of two-dimensional M-ary signaling in slow fading is presented and the exactaverage symbol error rate of coherent 16-star- QAM is obtained and compared to that of 16-rectangular-QAM.
Journal ArticleDOI
Cyclic prefixed single carrier transmission in ultra-wideband communications
TL;DR: The results demonstrate performance advantage of the SC-FDE scheme, especially when implementation issues such as low complexity and low power consumption for UWB are taken into consideration.
Journal ArticleDOI
Optimum Pulse Shaping in Digital Angle Modulation
G. Deshpande,P.H. Wittke +1 more
TL;DR: This paper presents a technique for optimizing the baseband pulse shapes in digital angle modulated signals to minimize the fraction of out-of-band power for a given channel bandwidth.
