Scalable Video Transmission Over Multi-Rate Multiple Access Channels

摘要

This effort demonstrated the interference mitigation capabilities of the auxiliary vector (AV) receiver for video transmission over direct-sequence code division multiple access (DS-CDMA) systems. The proposed receiver design is compared to the conventional RAKE matched-filter (RAKE-MF) and sample-matrix- inversion minimum-variance- distortionless-response (SMI-MVDR) receivers. The DS- CDMA video data stream is transmitted over an RF channel under realistic Rayleigh-faded multipath channel conditions, emulating open and/or urban battlefield environments.
