Abstract: Recently, sparse channel estimation in underwater acoustic orthogonal chirp-division multiplexing (OCDM) communication has attracted increasing attention. However, the channel estimation ...
Norsemont has completed nine drill holes totaling 2,187 meters so far in 2026, expanding work across five key zones at Choquelimpie. Early drilling has helped outline the edges of several hydrothermal ...
Abstract: Orthogonal time frequency space (OTFS) modulation is expected to address the performance degradation of orthogonal frequency division multiplexing (OFDM) modulated signals, particularly due ...
