Flexible Multi-Group Single-Carrier Modulation: Optimal Subcarrier Grouping and Rate Maximization

Yifei Yang, Shuowen Zhang, Joni Polili Lie, Rui Zhang

ICASSP 2018accepted

Orthogonal frequency division multiplexing (OFDM) and single-carrier frequency domain equalization (SC-FDE) are two commonly adopted modulation schemes for frequency-selective channels. Compared to SC-FDE, OFDM generally achieves higher data rate, but at the cost of higher transmit signal peak-to-av…

Low Complexity Implementation of Carrier and Symbol Timing Synchronization for a Fully Digital Downhole Telemetry System

Yifei Yang, Joni Polili Lie, Alberto Quintero

ICASSP 2018accepted

This paper presents a low complexity implementation of carrier phase and symbol timing synchronization on an OMAP-LI37 DSP-ARM dual core processor for a M -ary phase-shift-keying (M -PSK) based fully digital downhole telemetry system. The synchronization uses a data-aided algorithm (DA) that exploit…
