"abstract": "<p>Several new architectures are under investigation&nbsp;for cloud radio access networks, assuming distinct splits of&nbsp;functionality among the network elements. Consequently, the&nbsp;research on radio data compression for the fronthaul is based&nbsp;on assumptions that correspond to a wide variety of tradeoffs&nbsp;among data rate, signal distortion, latency and computational&nbsp;cost. This paper describes a method for LTE downlink point-topoint&nbsp;signal compression based on linear prediction and Huffman&nbsp;coding, which is suitable for low cost encoding and decoding units&nbsp;with stringent restrictions on power consumption. The proposed&nbsp;method can work at various compression factors, such as 3.3:1&nbsp;at an average EVM of 0.9%, or 4:1 at an average EVM of 2.1%.</p>",
