Quantization-Noise Suppression for Uplink eCPRI Assisted by Wireless-Channel Estimation Feedback
2018 European Conference on Optical Communication (ECOC), 2018 The behavior of quantization-noise in uplink eCPRI under the influence of wireless-channel fading is theoretically analyzed. And a noise-suppression method based on low-complexity DSP is demonstrated by standard-channel modeling and experimental transmission, which can reduce 6.5-dB noise power.
