Publication number: 20180288475Abstract: A receiver includes a plurality of input paths for receiving and processing a plurality of input RF signals. The input paths isolate one or more portions of corresponding ones of the received input RF signals, and combine the isolated portions of the corresponding ones of the received input RF signals onto one or more output signals. A bandwidth of the isolated portions of the corresponding ones of the received input RF signals and a bandwidth of the output signals are variable. The isolated portions of the corresponding ones of the received plurality of input RF signals are extracted and utilized to generate the output signals. The portions of the corresponding ones of the received plurality of input RF signals may be mapped into one or more channel slots in the time domain. The channel slots may be assigned in the frequency domain to one or more frequency bins.Type: ApplicationFiled: May 1, 2017Publication date: October 4, 2018Inventors: Sridhar Ramesh, Curtis Ling, Jingnong Yang

Patent number: 8134911Abstract: An OFDM-based device and method for performing synchronization utilizes a time-domain preamble of an incoming OFDM-based signal to compute an estimated fine frequency offset. The computation of the estimated fine frequency offset involves multiplying values of the time-domain preamble with conjugates of corresponding values of a selected base station time-domain preamble, averaging the resulting multiplied values in predefined segments and self-correlating the resulting averaged values to derive a self-correlation value, which is used to compute the estimated fine frequency offset.Type: GrantFiled: May 23, 2008Date of Patent: March 13, 2012Assignee: Amicus Wireless Technology Ltd.Inventors: Jingnong Yang, Won-Joon Choi

Patent number: 7912137Abstract: An Orthogonal Frequency Division Multiple Access (OFDMA) device and method of correcting frequency offset in OFDMA signals computes an estimated frequency offset, which is used for producing a frequency offset-compensated mixer signal using a reference clock signal. The frequency offset-compensated mixer signal is used to produce a digital down-converted signal from an incoming OFDMA signal. The digital down-converted signal is digitally corrected for sampling errors using the estimated frequency offset.Type: GrantFiled: January 10, 2007Date of Patent: March 22, 2011Assignee: Amicus Wireless Technology Ltd.Inventors: Chaohuang Zeng, Won-Joon Choi, Jingnong Yang
