Spectral characterisation of shortened pulse position modulation format [PDF]

, 2010
Shortened pulse position modulation (SPPM) is a new modulation format that has recently been proposed for underwater wireless optical communications. A full spectral characterisation of SPPM is considered and original expressions are presented, which ...

Vocalization Characteristics of the Indo‐Pacific Humpback Dolphins (Sousa chinensis) in Xiamen Bay With Insights on Regional Differences

Ecology and Evolution
Although whistles and high‐frequency clicks of Indo‐Pacific humpback dolphins (Sousa chinensis) had been documented in many wild populations, the small population inhabiting Xiamen Bay has received limited attention.
