IQ Data Compression Techniques for Bandwidth-Constrained Open Fronthaul
1. Introduction & Structural Background The transition from traditional monolithic Base Stations to disaggregated Open Radio Access Networks (O-RAN) has fundamentally reshaped the telecommunications industry. In a classic Distributed RAN (D-RAN), the baseband processing and RF frontends are tightly integrated using proprietary point-to-point protocols like the Common Public Radio Interface (CPRI). CPRI transmits continuous time-domain, uncompressed In-phase and Quadrature (IQ
