Latest Patents
One of Hee Gul Park's latest patents is titled "Apparatus and method for transmitting and receiving a RACH signal in SC-FDMA system." This invention provides an innovative approach to transmitting and receiving a random access channel (RACH) signal within an SC-FDMA system. The patent outlines a method where a frequency domain RACH signal is mapped to a localized sub-frequency band of the entire frequency band available to the SC-FDMA system. It also describes the allocation of a guard band, which includes at least one sub-carrier, between the RACH signal band and other channel signal bands. Additionally, a guard time is allocated between the RACH signal and other channel signals in the time domain. The RACH signal may contain a short message with information related to a mobile station. The detection of the RACH signal can be achieved through various methods, including frequency-based, time-based, or sliding matched filter-based methods. Notably, the complexity of the receiver can be reduced if the RACH signal incorporates a CAZAC code sequence for a preamble, allowing for more accurate adjustments of receive delays.
