ABSTRACT:
Cordless communication techniques for cordless communication devices having a handset unit and a base unit are provided. Such techniques can utilize a modulation method for Frequency Division Duplex/Time Division Duplex (FDD/TDD) that overcomes deficiencies of prior art devices, for example, by eliminating the need for a burst mode controller for both Frequency Division Duplex and Time Division Duplex, as well as surface acoustic wave bandpass filters and dielectric low pass filters.
