Spoofing Uplink Spatial Multiplexing With Diverse Spectrum
IEEE Transactions on Cognitive Communications and Networking, 2017 While 802.11 access points (APs) can have as many as eight antennas, form factor constraints often limit mobile clients to a single antenna, thereby precluding spatial multiplexing. In this paper, we design, implement, and experimentally evaluate diverse spectrum spatial multiplexing (DSSM), the first system to enable 802.11 standard-compliant uplink ...
