Abstract: If a PHS wireless LAN combo is constituted in which a PHS base station and a wireless LAN base station are placed in the same case, their frequency bands are different but they interfere with each other due to an influence of higher harmonics, which decreases communication efficiency. When a PHS base station is in a transmitting state and a wireless LAN base station is in a receiving state, a transmission signal from the PHS base station is multiplied by a predetermined attenuation ratio so as to subtract an attenuated value from a received signal of the wireless LAN base station, and when the wireless LAN base station is in a transmitting state and the PHS base station is in a receiving state, a transmission signal from the wireless LAN base station is multiplied by the predetermined attenuation ratio so as to subtract an attenuated value from a received signal of the PHS base station.

Abstract: A method and apparatus to perform a real-time drift correction of a remote handset's local oscillator in a digital cordless telephone. The remote handset begins in a standby (sniff) mode. The remote handset periodically wakes from a sleep mode and goes into a normal link verification mode. Once in the link verification mode, the remote handset enters a time division duplexing (TDD) mode and attempts to establish a link with a base unit based on the timing of the TDD data frame.

The remote handset implements a software frequency adjustment of its local oscillator. Once per frame, the remote handset enters a timing recovery state where the current state of the frame is compared with a previous state.

Abstract: Modern portable communications units, and in particular cellular telephones, can contain several frequency bands for receiving and several frequency bands for transmitting signals. Typically these units contain a baseband unit and a frequency synthesizer unit, which may be embodied as VLSI integrated circuits. The baseband unit commonly contains the user interfaces and control signals for controlling other portions of the circuitry. The second unit is sometimes called a frequency synthesizer unit. The second unit is dedicated to producing frequencies that are used by the communications system to create RF signals for broadcast and also to take RF signals and extract the modulated signal from them for decoding. As personal communications units have begun using an increasing number of bands it is often necessary to configure different filters to receive or broadcast the different bands. Typically, the baseband Integrated Circuit or separate circuitry does this filter configuration management.
