WANG Jun-xuan, LI Xiao-ping. Data Compression Technology Between BBU and RRU with Compressed Sensing[J]. 2016,(5):71-74. DOI: 10.13756/j.gtxyj.2016.05.021.
The influence of noise on the signal is small between the Base Band Unit and the Remote Radio Unit(BBU-RRU)in downlink and need a lot of space for storage.The sparseness of frequency domain of OFDM signal meets the requirement of the compressed sensing theory.Based on the above issues
this paper realizes OFDM signal reconstruction under different signal-tonoise ratios by using the compressed sensing theory.The simulation results show that this method can save nearly five times storage space of signal.Reconstruction signal has different damage rate and bit error rate under different signal-to-noise ratio
which meets the demand of communication system in the practical situation.
