DMMultipath

DMMultipath is a framework for exploiting multipath propagation in digital communication systems. It refers to methods that select, route, and combine multiple propagation paths to deliver data across a channel more reliably and efficiently than single-path approaches.

Concept: It relies on rapid channel estimation and path management. Signaling between transmitter, receiver, and network nodes to establish multiple usable paths; data is partitioned across paths with path-aware coding and modulation; synchronization across paths is maintained.

Techniques and components: path estimation and tracking (pilot-based), path selection and routing, multi-path scheduling, path-level interleaving and coding, and path combining at receiver (e.g., diversity combining or coherent aggregation). It may use OFDM or MIMO; CSI-based mechanisms to adjust per-path power and coding rates.

Applications: wireless access networks, backhaul, urban environments with heavy multipath; military communications; disaster-resilient networks.

Implementation considerations: latency, complexity, feedback overhead, hardware requirements; regulatory constraints; relationship to other concepts: expands on diversity, MIMO, equalization; not to be confused with multipath mitigation, which aims to minimize reflections.
