By using the $pm 2^{text {nd} }$ sideband modulation of DPMZM, the frequencies of RF signals are stretched.

As a result, the frequency resolution is enhanced with the time stretching of the mapped signal, without increasing the $2^{text {nd} }$ dispersion value of the dispersive media used for FTM.

By introducing photonic polarization multiplexing, the intermediate frequency (IF) signal and the local oscillator (LO) signal are modulated onto the orthogonally polarized optical carriers. The optical signal is transmitted over a long fiber to the remote base station, and then divided into two parts through a polarization beam splitter (PBS) following a polarization controller (PC). After photodetection, the two outputs are served as the transmitted signal and the reference signal for self-interference cancellation, respectively. The frequency up-conversion for transmitting, and the self-interference cancellation with high cancellation depth over a wide bandwidth for receiving are both achieved in the optical domain simultaneously. The independent photonic system for self-interference cancellation is avoided, guaranteeing the simplicity of the remote base station. The experimental results show that the cancellation depths of 30 dB over a 1-GHz bandwidth, and 26 dB over a 2-GHz bandwidth are realized.","PeriodicalId":211328,"journal":{"name":"2021 International Topical Meeting on Microwave Photonics (MWP)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133896975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
