"Pilot Pattern Optimization for Small Data Packet Transmission";
Talk: IEEE 26th Telecommunications forum TELFOR 2018, Belgrade; 11-20-2018 - 11-21-2018; in: "TELFOR 2018", Belgrade, Serbia (2018), 1 - 4.



English abstract:
We consider pilot pattern optimization for single
user single-input-single-output orthogonal frequency division
multiplexing transmission over doubly-selective channels, assuming
least squares channel estimation with linear interpolation
and extrapolation. Our focus is on small data
packet transmission which is typical for machine-type communications.
We compare diamond-shaped pilot patterns to
rectangular-shaped pilot patterns. We optimize the density
and spacing of pilot symbols in both pilot patterns with
respect to the constrained capacity and demonstrate that the
rectangular pilot pattern can outperform the diamond-shaped
pattern in case of small data packet transmission.
