Optimal Fronthaul Quantization for Cloud Radio Positioning
The design of a wireless positioning system that is implemented by means of a Cloud Radio Access Network (C-RAN) is investigated. The C-RAN under study consists of a single cluster of distributed Radio Units (RUs), which are managed by a centralized Control Unit (CU). The RUs are synchronous and compress the received baseband signals, which are then forward to the CU over finite-capacity fronthaul links. The CU determines the position of the target, e.g., a mobile station, based on the compressed baseband signals.
