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

Channel estimation based on superimposed pilot (SP) is a challenge in orthogonal
frequency division multiplexing (OFDM) systems. To reduce the pilot data interference in the …

Constant envelope orthogonal frequency division multiplexing (CE-OFDM) is a multi-carrier
waveform with 0 dB peak-to-average power ratio (PAPR). This property enables the …

Superimposed training (ST) is one of the most appealing channel estimation techniques for
orthogonal frequency division multiplexing (OFDM), to be possibly exploited in the 6G. The …

Superimposed Training (ST) with orthogonal frequency division multiplexing (OFDM)
scheme has become an attractive solution to meet the goals of the fifth generation (5G) of …

Pilot-pouring superimposed training (PPST) is a novel channel estimation technique
specially designed for cyclic block filtered multi-tone (CB-FMT), where the pilot symbols are …

In this paper, channel estimation capabilities of a multiple-input multiple-output (MIMO)
system using superimposed training sequences are investigated. A new expression for …
