Title: **The Innovative Mind of Junmo Sung in Wireless Communication**

Introduction:

Junmo Sung is an accomplished inventor based in Austin, TX, renowned for his contributions to wireless communication technologies. With a total of three patents to his name, Sung has significantly impacted the field, particularly through innovative solutions aimed at enhancing the efficiency of MIMO (Multiple Input Multiple Output) wireless communication systems.

Latest Patents:

One of Junmo Sung's latest patents focuses on **UE-aided channel reciprocity compensation for radio access in MIMO wireless communication systems**. This invention involves a wireless cellular base station transmitter that sends a downlink calibration pilot symbol. A receiver subsequently collects an uplink calibration pilot symbol and an effective downlink channel estimate from user equipment (UE). The UE calculates this effective downlink channel estimate based on the downlink calibration pilot symbol received from the base station. Processing devices within the base station then compute an effective uplink channel estimate and derive channel reciprocity calibration coefficients using both effective downlink and uplink channel estimates. Notably, the base station is equipped with multiple antennas and computes calibration coefficients for each one. Alternatively, the uplink channel estimate may be seen as an inverted version of the effective downlink channel estimate, which aids in channel reciprocity compensation.
