摘要： The present invention relates to a transceiver for bidirectional frequency division multiplexed transmission, a communication system including one or more transceivers. Optionally, the communication system is a communication system for a digital subscriber line. The transceiver comprises transmission means with a voltage source output or a current source output for transmitting data in a transmission frequency range, receiving means for receiving data in a receiving frequency range, and a coupling impedance for connecting the transmission means and the receiving means to a transmission medium. The magnitude of the coupling impedance in the transmission frequency range is smaller than the magnitude of the coupling impedance in the receiving frequency range if the transmission means has a voltage source output and is higher than the magnitude of the coupling impedance in the receiving frequency range if the transmission means has a current source output.

摘要： A method is provided for recognizing the frequency bandwidth of a base station in a mobile communication system with frequency bandwidth scalability where the transmission frequency bands of base stations and mobile stations having different frequency bandwidths are overlaid with one another. The base stations transmit to a mobile station first information, including information about their frequency bandwidths at the same frequency position over a minimum frequency bandwidth with the same center frequency. The mobile station recognizes the presence of the base stations by comparing the first information from the base stations and detects the frequency bandwidth information in the first information.

摘要： A cordless telephone system comprising a handset and a base station. Each of the handset and the base station contains a transmitter and a receiver, preferably operating on different frequencies. At least one of the handset and the base station controls frequency hopping based on a signal received from the other of the handset and the base station. In a preferred embodiment, The handset transmitter transmits to the base station a combined signal including a digital portion and an analog portion. The base station separates the combined signal to recover the digital portion and the analog portion and employs the analog portion to convey communicated information and the digital portion to control frequency hopping in the transmitter of the base station. The handset transmitter provides a local oscillator signal to the handset receiver to enable frequency conversion in the handset receiver. The base station transmits to the handset a similar combined signal which is similarly separated and employed by the handset.

摘要： A first copy and a second copy of a signal, which comprises a plurality of TDMA frames, are transmitted from the same antenna. Relative to the first copy, the second copy of the signal has a fixed delay and a random phase. The random phase changes from one of the TDMA frames to another of the TDMA frames. A group of hopping carrier frequencies are partitioned into at least two sets of carrier frequencies. The first copy and the second copy of the signal are transmitted using a sequence of the hopping carrier frequencies, wherein consecutive pairs of the hopping carrier frequencies for consecutive pairs of the TDMA frames are not from the same one of the at least two sets.

摘要： A communication device locates a wireless service provider in a multi-service provider environment using a frequency band search schedule. The frequency band search schedule has a first or home band and a several other frequency bands in a predetermined ordered. The order of the frequency bands may be programmed by the user or by a home service provider over the air. The communication device searches for an acceptable service provider by examining the home band and then the other bands listed in the frequency band search schedule. The bands are examined in the order specified by the frequency band search schedule. An acceptable service provider is identified by comparing the identify of a service provider specified by an identifier received from a band being examined with a list of acceptable service providers.

摘要： Disclosed herein is an interlaced frequency division duplexing method for a duplex communication system. The present invention is constructed to estimate feedback information of a transmission frequency channel using a reception frequency channel. In the interlaced frequency division duplexing method, a frequency band of the duplex communication system is divided into a plurality of frequency channels so as to guarantee similarity between channel characteristics of neighboring frequency channels. Transmission and reception channels are alternately allocated to the plural frequency channels. Accordingly, the present invention can allow a transmitting end of the duplex communication system to easily estimate the variation of feedback information due to the variation of channel characteristics without reducing transmission efficiency under a time-varying multi-path channel environment, and which can prevent the performance of the duplex communication system from being deteriorated due to the variation of channel characteristics.
