摘要： A receiver restores a transmitted information bit series accurately by performing maximum-likelihood series estimation. The operation of the receiver includes estimating characteristics of a transmission line for each symbol based on the amplitude and phases of pilot symbols which are extracted from reception symbol groups, calculating weighting factors showing the reliability of the transmission line in symbols based on the estimation result and the reception symbol groups, multiplying each symbol of information symbol groups which are extracted from the reception symbol groups by the weighting factors to reflect the transmission-line reliability in symbols, and restoring an information bit series by applying maximum-likelihood series estimation to coded bit groups restored from the information symbol groups on which the reliability is reflected.

摘要： In a filter device a reference clock generator produces a reference clock signal having the stated frequency; a data signal generator generates a data signal which is asynchronous with the reference clock signal; trigger signal generator produces a trigger signal when a discrepancy which exceeds the interval of one clock of the reference signal occurs between the reference clock signal and the data signal; and a digital circuit re-samples the data signal in accordance with the reference clock signal and changes the magnification ratio of the re-sampling by increasing or reducing the sampling period of re-sampling by one clock interval of the reference signal. By changing the magnification ratio of the re-sampling on only the occasion of such a timing that a temporal discrepancy between the reference signal and the data signal has been detected, it can correct the temporal discrepancy which is due to the fact that the frequencies of the reference signal and the data signal are asynchronous with each other and can prevent spectral distortion of the transmission signal, and also it can utilize the reference signal, which is asynchronous with the data signal, for production of the transmission signal without any trouble.

摘要： A learning on a weight of an adaptive array antenna which becomes necessary for a space division multiple access is carried out while a backward compatibility with a conventional standard is maintained.When a TRQ frame and a training frame for the learning are exchanged, a spoof is applied on these frames to preferably avoid collisions with a surrounding station STA4 that follows a conventional standard. Also, after the weight of the adaptive array antenna is learnt, a STA0 multiplexes and transmits the plurality of data frames addressed to a plurality of users while a wireless resource on a spatial axis is shared by the plurality of users, so that a throughput for one-to-many, that is, for the plurality of users as a whole is improved.

摘要： Access control based on CSMA is favorably carried out with the RTS/CTS method used together.If the RTS/CTS procedure is used together, CTS information is transmitted in response to the reception of RTS information, and data is transmitted in response to the reception of CTS. The CTS transmitting station measures the quality of RTS receive signal, and thereby determines a transmission rate at which it can receive and notifies a station as the destination of CTS. The station as the destination of CTS transmits data in response to CTS information. As the transmission rate for this data, the transmission rate indicated in the RATE field in CTS is applied.

摘要： The present invention eliminates a transmission-waiting operation which is unnecessary while accommodating a prioritized traffic. Although a communication station enters a transmission-disallowed state in response to detection of a signal addressed to another station in accordance with medium access control based on CSMA, if the communication station receives a frame transmitted with priority to a local station during the transmission waiting, it cancels the transmission-disallowed state, sends back a frame responding the frame transmitted with priority and effectively operates a transmission prioritized period. The communication station starts a search procedure to perform a processing of evading duplication of the transmission prioritized periods if it judges a possibility of a problem occurring in a time zone in which reception with priority is possible.

摘要： Communication stations in a network each transmit a beacon signal that includes network information. The beacon signal sets a state in which a reception operation is performed, before and after the transmission of the beacon signal. The reception operation occurs during access control, so as to avoid collision with communication timings of packets from another communication station, by detecting signals transmitted from other communication stations. States set in the communication stations are transitioned between a transmission state and a reception state based on a fluctuating volume of transmission and reception data. Data accumulations at transmitting communication stations and delays at receiving communication stations are reduced, and low latency data transfer is achieved using minimal levels of transmission and reception operations.
