摘要： PROBLEM TO BE SOLVED: To provide an apparatus and method for detecting a path capable of reducing the computing complexity at path selection, surely selecting a path and reducing an error rate in received data.
SOLUTION: An adjacent sample comparison processing section 201 compares the power values between adjacent samples of a delay profile generated on the basis of a received signal subjected to oversampling to detect whether power values are increasing or decreasing. A comparison result storage processing section 204 sets 1 to a flag when the present information is the same as the preceding increase / decrease information of the power values between the adjacent samples, and resets the flag and newly set 1 to the flag when the information is different. A slope discrimination processing section 205 controls a path selection section 207 to select a corresponding sample to be a path when the count is equal to the number of oversampling times. The path selection section 207 selects a sample with a maximum value for a path object and also selects a sample instructed from the slope discrimination processing section 205 as a path.

摘要： PROBLEM TO BE SOLVED: To provide a communication apparatus for improving the certainty and security of communication. SOLUTION: A wireless terminal 100 is provided with: a transmission propriety discrimination section 186 for controlling transmission timing of transmission data on the basis of an AIFS and a back-off value; and an AIFS management section 181 for adjusting an AIFS value with respect to the transmission data in response to n elapsed time from the occurrence of a transmission request of the transmission data. Thus, a smaller AIFS setting value is set to the transmission data with a longer elapsed time from the occurrence of the transmission request of the transmission data, and a prescribed waiting time obtained from the AIFS value and the back-off value is also set smaller. Since the transmission data can be transmitted with higher priority than that of other transmission data, the possibility of the transmission data being aborted by time-out is set lower. As a result, the certainty and stability of communication is enhanced. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To estimate a spread code multiplexed with a received signal with high accuracy even when a plurality of objects of the number of spread codes corresponding to a midamble shift exist.
SOLUTION: An inverse spread/RAKE composite section 107 uses all spread codes to apply despread processing to a data part and to apply RAKE composite to the despreading signals. An average value calculation section 108 calculates an average on the basis of the result of RAKE composition. An average value sort section 109 sorts RAKE output average values by all spread codes in the descending order. A threshold setting section 110 uses a minimum value of the RAKE output average values by a plurality of spread codes assigned to its own station for a threshold setting reference value and sets a threshold at a position decreased from the reference value by a prescribed width. A spread code discrimination section 111 applies threshold discrimination between the threshold and the RAKE output average value obtained from the spread codes other than the spread code assigned to its own station. A JD (Joint Detection) arithmetic section 112 uses the spread code multiplexed with the received signal to perform the JD arithmetic operation.
