Abstract

In this paper we report results from the Calibration and Communications Sea Trial 2010. We explain in detail the used cyclic-prefix orthogonal frequency division multiplexing (OFDM) signal design and adopted receiver processing, based on sparse channel estimation and intercarrier interference (ICI) equalization. We then focus on two phenomena that are not commonly treated in wireless communications literature, namely, colored noise due to (partially) untreated ICI and narrowband interference, and biased symbol estimates due to noisy channel estimates used in multi-phone combining.
