An 0.8-mm(2) 9.6-mW Iterative Decoder for Faster-Than-Nyquist and Orthogonal Signaling Multicarrier Systems in 65-nm CMOS
(2013) In IEEE Journal of Solid-State Circuits 48(7). p.1680-1688- Abstract
- This paper presents an iterative decoder for faster-than-Nyquist (FTN) and orthogonal signaling multi-carrier systems. FTN signaling is a method of improving bandwidth efficiency at the expense of higher processing complexity in the transceiver. The decoder can switch between orthogonal and FTN signaling modes and exploits channel properties to improve bandwidth efficiency. The decoder is fabricated in a 65-nm CMOS process and occupies a total area of 0.8 mm(2) with decoder core taking up 0.567 mm(2). The power consumption of the chip is 9.6 mW at 1.2 V when clocked at 100 MHz, providing a peak information throughput of 1 Mbps and with an energy efficiency of 0.6 nJ per bit per iteration. To the best of our knowledge, those measurement... (More)
