摘要： An AGC unit starts a gain control of the variable gain amplifying unit when a bit saturation occurs in the digital baseband signal output from the A/D converting unit, and starts a gain control of the variable gain amplifying unit when a detection of STS from the digital baseband signal output from the A/D converting unit is started. The AGC unit performs the gain control of the variable gain amplifying unit once when the detection of STS is started, and performs the gain control of the variable gain amplifying unit twice when the bit saturation occurs, namely a larger number of times than when the detection of STS is started.

摘要： In a wireless communication system according to the present invention: a control device and a communication terminal communicate in an active period. The control device: generates a first beacon packet including one or more candidate channels; transmits the first beacon packet at the beginning of the active period; determines whether or not a use channel is to be changed based on a communication state, and generates a second beacon packet including information of a determination result; transmits the second beacon packet at the end of the active period; and, when it is determined that the use channel is to be changed, changes the use channel after the active period ends and before a next active period starts. The communication terminal: receives the first and second beacon packets; and, based on the second beacon packet, changes the use channel after the active period ends and before a next active period starts.

摘要： A correlation unit (32) sequentially obtains correlation values between a baseband signal and a reference signal and outputs the obtained reference signal to a section division unit (33). The output of the correlation unit (32) is divided into symbol time periods by the section division unit (33). A section position detection unit (34) detects a largest correlation value in each of sections resulting from the division by the correlation unit (32) and outputs, to a synchronization judgment unit (35), first position information that indicates a relative position of each detected largest correlation value. The synchronization judgment unit (35) detects an arrival of a packet signal and estimates a symbol timing based on the first position information of the sections.

摘要： A beacon is transmitted and received among a plurality of terminals STA. A terminal STA which transmits the beacon is assigned as a representative terminal MSTA which manages a group, and a terminal STA which receives the beacon is assigned as a belonging terminal SSTA of the group. The representative terminal MSTA obtains identification information from the belonging terminal SSTA and stores the identification information. Then, when receiving an AP beacon from a management terminal AP, the representative terminal MSTA collectively transmits, to the management terminal AP, the identification information of the representative terminal MSTA and the belonging terminal SSTA. The management terminal AP performs an authentication procedure, by using the collectively transmitted identification information, for each of all of the communication terminals which form the group.

摘要： Provided is a compact and low power consumption wireless communication system, including a base station and communication terminals, in which power consumption of the communication terminal is reduced. The base station alternately sets an active interval during which predetermined data communication is performed, and an inactive interval during which the predetermined data communication is not performed. During the active interval, a beacon including information indicating a start timing of a subsequent active interval is transmitted and received. During the inactive interval, a sub-beacon including information providing notice of a transmission timing of a subsequent beacon is transmitted and received. When receiving the sub-beacon, the communication terminal obtains the transmission timing of the subsequent beacon and stops a supply of power to an unit related to a wireless communication function until the transmission timing.

摘要： An FFT unit (170) separates a received symbol by Fourier conversion into a plurality of subcarriers, and a phase difference detection unit (193) detects a phase difference between 4 pilot carriers and data carriers adjacent to the pilot carriers (adjacent carriers) The decision unit (194) decides whether the phase differences between the pilot carriers and the adjacent carriers detected by the phase difference detection unit (193) fulfill a phase difference condition. Then, the decision unit (194) decides that the received symbol is an HTSIG if the number of phase differences that fulfill the phase difference condition is greater than or equal to a predetermined number, and decides that the received symbol is either a SIG or a DATA if the number of phase differences that fulfill the phase difference condition is less than the predetermined number.
