WOTM-LD

WOTM-LD is an acronym used in the field of radio communications and signal processing, specifically related to Wideband Orthogonal Time-domain Multiplexing with Low Density (WOTM-LD).

WOTM is a multiplexing scheme designed to transmit multiple data streams simultaneously over a wide bandwidth. Orthogonal Time-domain Multiplexing (OTM) is a technique where different data streams are modulated and transmitted within non-overlapping time slots, ensuring orthogonality and minimizing inter-symbol interference.

The "LD" suffix signifies "Low Density." This refers to the sparsity of the time-domain representation or a low duty cycle transmission strategy. The term can represent techniques employed to reduce power consumption or interference within the communication system. This could be achieved through mechanisms such as employing a low fill factor, or sparsely populating time slots with data. Low density transmission may also be used to facilitate spectrum sharing or to operate in environments where interference avoidance is paramount.
