Orthogonal frequency division multiplexing (OFDM) has been widely adopted in modern
wireless communication systems due to its robustness against the frequency selectivity of …

Multicarrier modulation allows for deploying wideband systems resilient to multipath fading
channels, impulsive noise, and intersymbol interference compared to single-carrier systems …

Orthogonal frequency-division multiplexing (OFDM) effectively mitigates intersymbol
interference (ISI) caused by the delay spread of wireless channels. Therefore, it has been …

This paper analyzes the fundamental trade-offs that occur in the co-design of pilot resource
allocations in orthogonal frequency-division multiplexing signals for both ranging (via time-of …

In this study, the noise variance and channel estimation problems are investigated over the
UWB channel with narrowband interference (NBI). We first give two ways to construct the …

A decision-directed (DD) channel estimation based on iterative linear minimum mean
