An adaptive control system for controlling the effects of narrow to medium bandwidth interferers in a wireless communications system (e.g., wireless LAN devices) by identifying which sub-carriers in a multi-carrier system are located on frequencies that are subject to interfering signals, and using only those sub-carriers that are not subject to interference for communications between wireless communications devices.

A boost converter utilizing bi-directional magnetic energy transfer of coupling inductor provides a high efficiency boost DC-DC converting with above 30 times voltage boost rate, which uses a coupling inductor and low voltage switch to absorb circuit induction voltage of a passive regenerative snubber no matter if switch is turned on or off. Such that, a much higher voltage boost rate than the turn rate of transformer and wider range of switching duty cycle is obtained. A bi-directional magnetic energy path is utilized, that is, when switch is turned on the first winding of coupling inductor stores magnetic excited high current energy, and opposite magnetic flux is induced on the second winding at the same time. When switch is turned off the magnetic excited current continues and increases the voltage on the second winding. The second winding has bi-directional magnetic current induced and fully utilizes capacity of transformer's iron core.

A protocol is proposed for a mobile station to transmit Dual Tone Multi-Frequency (DTMF) to another mobile station. When a user presses a key on a source mobile station, which is connected to a target mobile station, DTMF data are transmitted via a digital channel to a base station first. Instead of converting the received DTMF data to a corresponding analog voice to the target mobile station, the base station forwards the DTMF data to the target station via a digital channel. The target mobile station parses the DTMF data and activates certain operation in response to the key pressed by the user.
