The long-term evolution (LTE) transports complex-baseband samples between the remote radio head and baseband processing unit. Common public radio interface (CPRI) protocol is used in practice and enables flexible radio head deployments and distributed antenna systems. Current wireless links (FSO and mmWave) have a few Gb/p transmissions which insufficient capacity are to support 20 MHz bandwidth LTE with multiple sectors. In this presented work, we propose a compression algorithm uses non-quantized Huffman. The proposed technique achieves 78% compression ratio while maintaining with EVM less than 3%. © 2018 IEEE.
