Analog Subspace Coding: A New Approach to Coding for Non-Coherent Wireless Networks

Understand

We provide a novel framework to study subspace codes for non-coherent communications in wireless networks.

• To this end, an analog operator channel is defined with inputs and outputs being subspaces of $\mathbb{C}^n$.
• Then a certain distance is defined to capture the performance of subspace codes in terms of their capability to recover from interference and rank-deficiency of the network.
• We also study the robustness of the proposed model with respect to an additive noise.
