In-band interference reduction using Minimum Norm method in frequency modulated continuous wave channel data

摘要

An in-band interference occurs when a part of transmission band is simultaneously used by another application and raise the noise floor and reduce signal ratiooise ratio(SNR). In channel sounding, measurement campaigns are expensive and difficult to repeat since every channel data is valuable for a sound channel. In this study ‘Minimum Norm’ method was used to reduce the effect of interference in the frequency modulated continuous-wave (FMCW) channel data. The minimum norm method reduced the noise floor by about 20 dB for the channel data with in-band interference.
