Abstract:
A time division multiple access (TDMA) base station for preserving across-slot signal continuity of signals transmitted in different directions on a given frequency, comprising:a multi-directional antenna for radiating signals; a processor operatively coupled to the antenna for generating a first data signal for a first time slot of a TDMA frame including a first predetermined symbol pattern and a second predetermined symbol pattern, for generating a second data signal for a second time slot of the TDMA frame including the second predetermined symbol pattern, and for communicating the first data signal and the second data signal to the antenna such that the first data signal is radiated in a first direction and the second data signal is radiated in a second direction; and wherein the first data signal is modulated at a first phase for transmission in the first time slot at a first power level in the first direction on the given frequency, and the second data signal is modulated at a second phase for transmission in the second time slot at a second power level in the second direction on the given frequency.
