BFP IQ Compression

General Description

The BFP IQ compression IP core is a silicon agnostic implementation of a lossy Block Floating Point compression and de-compression scheme that improves fronthaul bandwidth efficiency.

The IP has been designed to conform with the O-RAN CUS-plane protocol standard v2.0 but can also be used in any arbitrary system where fronthaul bandwidth is a limiting factor. The IP core enables quick and reliable deployment of compression and de-compression at both radio and baseband side and can be configured to handle any kind of fronthaul implementation.

The core can either be used in a 5G/4G radio mode where compression is made on larger blocks, e.g. Resource Blocks, or as a single unit that performs compression on a sample by sample basis.
