Optimal-Access Cooperative MSR Codes: Parity-Check Matrix Construction And a Unified Transformation
Yaqian Zhang, Jingke Xu, Ya-Feng Liu
Cooperative MSR codes are a kind of storage codes which enable optimal-bandwidth repair of any node erasures in a cooperative way, while retaining the minimum storage as a…
Joint Beamforming and Compression Design for Per-Antenna Power Constrained Cooperative Cellular Networks
Xilai Fan, Ya-Feng Liu, Bo Jiang
In the cooperative cellular network, relay-like base stations are connected to the central processor (CP) via rate-limited fronthaul links and the joint processing is performed at…
