Broadcom Corporation Receives Patent for Advanced Wireless Communication Method

Strategic Insights -

Broadcom Corporation has been granted a patent by the United States Patent and Trademark Office for an innovative method and system for enhancing wireless communication in Time Division Duplex (TDD) Multiple-Input Multiple-Output (MIMO) systems. The patent, titled "Method and system for a double search user group selection scheme with range reduction in TDD multiuser MIMO downlink transmission," was awarded patent number 8,934,432 on January 13, 2015.

This breakthrough involves maximizing system capacity by reducing the search range within which to find signals with maximum channel gain. By implementing a double search user group selection scheme, the system can efficiently select signals that provide the maximum system capacity. This technology has significant implications for the development of high-capacity wireless communication systems.

Key Takeaways:

  • The patent, titled "Method and system for a double search user group selection scheme with range reduction in TDD multiuser MIMO downlink transmission," was granted to Broadcom Corporation, and the inventors behind the technology are Jun Zheng, Chengjin Zhang, and Pieter van Rooyen.
  • The patent involves using a double search user group selection scheme to reduce the search range and find signals with maximum channel gain to maximize system capacity.
  • The system involves selecting at least one of a first signal for a first user and a second signal for a second user within the reduced search range, which provides the maximum system capacity.
  • The reduced search range is generated by sorting a plurality of signals based on a channel gain corresponding to each of the plurality of signals.
  • Broadcom Corporation filed the patent application on September 12, 2012.
  • The patent was awarded patent number 8,934,432 on January 13, 2015.
