Efficient computation of the binary vector that maximizes a rank-deficient quadratic form
The maximization of a full-rank quadratic form over a finite alphabet is NP-hard in both a worst-case sense and an average sense. Interestingly, if the rank of the form is not a ...

Optimal Pilot Symbol Distribution for Efficient and Low-Complexity Doppler-Shift and Doppler-Rate Estimation in Bursty Transmiss
— Due to relative motion between the transmitter and the receiver, the carrier of the received signal in digital burstmode transmission can be affected by Doppler distortion. Thi...
