Patent number: 9912786Abstract: A demodulation section demodulates a received signal. A decoding section decodes an output from the demodulation section. A buffer temporarily stores a portion of the received signal. A header analyzing section gives the buffer timing at which demodulation and decoding of a payload of the received signal are initiated, on the basis of a result of combination of a plurality of header sequences included in a header of the received signal and results of processing of the demodulation section and the decoding section. An improved SNR is achieved by means of combination of the plurality of header sequences, so that an iterative decoding count used for decoding the header become smaller.Type: GrantFiled: February 27, 2013Date of Patent: March 6, 2018Assignee: PANASONIC CORPORATIONInventors: Naoya Yosoku, Hiroyuki Yoshikawa, Naganori Shirakata
