Abstract:
Next-generation satellite communication systems require high spectral efficiency to meet future data rate requirements. Faster-than-Nyquist signaling offers improvement potential by exploiting excess bandwidth of the transmit pulses at the price of inter-symbol interference. This paper studies sophisticated receiver structures that lead to linear discrete minimum phase models with uncorrelated noise. They enable equalization of inter-symbol interference with feasible complexity in trellis-based decoders. Another challenge is nonlinear distortion in the transmit signal caused by the satellite’s high power amplifier. The distortions are accounted for using a linearized Volterra filter model. Finally, a comparison to conventional methods shows that the new approach yields considerable performance gains.
