“Fronthaul Compression for Cloud Radio Access Networks”
- Multiterminal compression
Uplink: The key technique is distributed compression or Wyner-Ziv coding[10].
Downlink: multivariate compression [9 Ch.9].
- Structured coding
compute-and-forward[11]
- Uplink:
- Distributed Fronthaul Compression
First proposed in [17].
sequential decompression [9, Ch. 10] [18] [19].
Wyner-Ziv compression.
channel decoding algorithms: message passing or trellis search[10].
optimization problem of this scheme: block-coordinate optimization approach and leverages a key result in [20].
- Compute-and-forword [11]
