u-law IQ Compression

General Description

The IQ compression IP core is a silicon agnostic implementation of a compression and de-compression scheme enabling doubling data capacity on exiting CPRI or Ethernet based links or alternatively running lower speed links between remote radio units and baseband cards with the same radio ressource capacity. The compression IP handles any radio channel bandwidth and operates on time-domain IQ samples with minimal loss.

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.
