Static Multislit Spectrometry and Its Application to the Panoramic Display of Infrared Spectra*

A MIMO-OFDM channel estimation scheme utilizing complementary sequences

“…In this paper, we propose a simpler and computationally efficient method to obtain the sampled channel estimates using pilots without any need for initialization symbols or extra processing at the receiver. Our method uses OSTBC (Orthogonal Space-Time Block Coded) transformed Golay complementary sequences [5] to design pilots in the frequency domain. A lower bound on the number of pilots needed to estimate the frequency selective channel is derived and it has been shown that this channel estimation strategy can be used with transmit and receive antenna arrays of arbitrary sizes.…”

Golay complementary array pairs

“…Such a pair of sequences is called a Golay complementary sequence pair (often abbreviated to Golay sequence pair) of length s, after Golay [14], [15]; Shapiro [24] independently studied the same object. The initial investigation of Golay sequence pairs was restricted to the binary case.…”

Instantaneous Radar Polarimetry with Multiple Dually-polarized Antennas

“…Howard et al [3] employ Golay pairs of phase-coded waveforms [10], [11] to provide synchronization and enable use of the Alamouti space-time code [12] to coordinate transmission of Golay pairs across polarizations. The use of Golay pairs and Alamouti signal processing enables radar ambiguity polarimetry on a pulse by pulse basis and allows for estimating the full polarimetric properties of the target, at computational cost comparable to single channel matched filtering.…”
