Abstract

Correct estimation of symbol timing, Carrier Frequency
Offset (CFO), and Signal-to-Noise Ratio (SNR) is crucial
in Orthogonal Frequency Division Multiplexing (OFDM) communication.
Typically, high estimation accuracy is desired, but often
comes with increased complexity. Which has a direct repercussion
in energy consumption. In this article, an architecture based on
Sign-Bit estimation with low complexity, and hence low power
dissipation, is presented. The architecture, is capable of estimating
the afore-mentioned parameters in virtually any OFDM
standard. The proof of concept has been fabricated in 65 nm
CMOS technology with low-power high-VT cells. Measurements
performed with supply voltage of 1.2V. resulted in a power
dissipation of 350 μW, 6 times smaller to that of an equivalent
8-bit architecture, and the lowest power density reported in
literature.
