NTT DOCOMO announced today that it has successfully developed a trial large-scale-integration (LSI) chip that consumes less than 0.04 W of power yet supports multiple-input multiple-output (MIMO) signal detection and decoding for downlink transmissions at 100 Mbps, the speed required for the forthcoming mobile system known as Super 3G, or Long Term Evolution (LTE). In the new chip, which is made with 65-nanometer processing, the circuits have been further optimized, particularly by eliminating redundant circuits for computationally complex processes such as MIMO-signal detection and error-correction decoding.

DOCOMO will incorporate its new LSI chip technology in ongoing research and development of LTE and International Mobile Telecommunications-Advanced (IMT-Advanced) systems, as well as in its active support of the establishment of related international standards.
