This paper presents a performance comparison of impulse radio ultra wideband (IR-UWB) and multi-band orthogonal frequency division multiplexing (MB-OFDM) for multi-user wireless communication systems. Focusing on the analysis of system performance affected by multi-user interference (MUI) over general additive white Gaussion noise (AWGN) channel, we run a complete system simulation for direct sequence...
Low Rate Orthogonal Convolutional Codes (LROCC) have been confirmed an outstanding performance in AWGN channel with multiple users, such as the en-route situation in the aeronautical communications with several aircrafts. However, the orthogonal sequences in LROCC still suffer from multipath interference in fading channel, which degrades the performance in practical scenarios. In this paper, extended...
Amplitude phase-shift keying (APSK), especially 16APSK and 32APSK modulations, have been efficiently applied into satellite broadcasting and communications, such as DVB-S2, which endows the system with high spectrum efficiency and transmission rate. However, fewer design about the trellis coding and modulation based on APSK has been reported so far. In this paper, the symmetric and asymmetric TCM...
