Recent Advances in Doppler Resilient Sequence Design and Applications

Abstract: Sequences with good correlation properties play a vital role in wireless communications, radar sensing, and cryptography. To estimate the range of a target from a radar based on the delay in the radar return, or to synchronize a mobile handset with a pilot signal sent from a base station, it is required to design sequences with impulse-like autocorrelation functions, such as Golay complementary sequences or zero correlation zone (ZCZ) sequences. Typically the estimation/synchronization is performed by matched filtering the received signal with the transmitted waveform, and the output of the matched filter would ideally be an impulse at the desired delay. However, the autocorrelation property of the Golay, ZCZ and other sequences is extremely sensitive to Doppler shift caused by the highly mobile target/handset. Although the effective ambiguity function of complementary sequences is free of delay (range) sidelobes along the zero-Doppler axis, it has large-range sidelobes off the zero-Doppler axis. In recent years, there are significant advances in Doppler resilient sequence design and applications. In this talk, the existing and new methods to construct Doppler resilient sequences based Golay and Z-complementary sequences will be discussed, together with the related applications in MIMO radar, cognitive radio and high mobility communications.

Recent Advances in Sparse Coded Multiple Access



Zheng Ma

Abstract: As a novel multiple access technique, Sparse Coded Multiple Access (SCMA) enables the non-orthogonal design among code and power domain, which could improve the capability largely. Due to the sparsity, the low complexity message passing algorithm (MPA) can be adopted and near maximum likelihood (ML) performance for multi-user detection can be achieved. In this chapter, the system model and general description for SCMA are given. The codes design and multi-dimensional constellations design are discussed. Several low-complexity multi-user detection approaches are introduced. The performance analysis for SCMA, such as pairwise error probability (PEP) and capacity are conducted.
