High data rate spatial multiplexing implementation for multiple antenna systems

 

Technology overview

Non-Orthogonal Spatial Multiplexing (NOSM) is a software-based solution designed to achieve spatial multiplexing gains in line-of-sight wireless environments with poor scattering. It operates by transmitting and receiving data streams, utilizing advanced signal processing techniques to minimize signal interference between transmitted data. The technology is frequency-independent across various radio frequency bands and scales data rates proportionally to the number of antennas. NOSM requires no additional equipment, bandwidth, or costly tower-leasing fees. It acts as a cost-effective software upgrade that nearly doubles throughput, demonstrating a 1.98x bit rate improvement in a standard 2x2 setup. Furthermore, NOSM uniquely leverages its extra data capacity to enhance network security, such as utilizing one stream as an encryption key for another.

Market applications

  • Terrestrial wireless backhaul links
  • Satellite to ground communications
  • Satellite to aircraft links
  • Direct to device satellite links
  • Wi-Fi network extension

Competitive advantage

  • Reduces operational and regulatory costs by avoiding extra hardware tower leasing and spectrum fees.
  • Significantly increases data throughput and nearly doubles bit rates in standard 2x2 MIMO systems and scales proportionally with the number of antennas without requiring extra bandwidth.
  • Operates without additional hardware and integrates directly into existing radio infrastructure
  • Improves performance in Line-of-Sight (LoS) environments where traditional MIMO struggles
  • Enables deployment across multiple radiofrequencies.

Business opportunity

  • Partnership for R&D collaboration and/or licensing
