CDMA/OTFS Sensing Outperforms Pure OTFS at the Same Communication Throughput
There is a dearth of publications on the subject of spreading-aided Orthogonal Time Frequency Space (OTFS) solutions, especially for Integrated Sensing and Communication (ISAC), even though Code Division Multiple Access (CDMA) assisted multi-user OTFS ...

Blind estimation of spreading sequence of CDMA signals based on Fast-ICA and performance analysis
The DS-CDMA signals can be divided into two types,the short-code(SC) and the long-code(LC) DS-CDMA signal.The existing methods are only used to estimate spreading sequences of SC-DS-CDMA signals,which cannot work for the LC-DS-CDMA signals.A new blind ...
