ABSTRACT:
An improved antenna diversity system is provided. The antenna diversity system has at least two spaced-apart antennas, with each antenna providing a respective antenna signal. The signal(s) may be processed and scaled according to its respective power level. The phase difference is determined between the signals, and the phase difference reduced by using phase rotation. The signals, which are now substantially in-phase, are summed to generate a combined antenna signal.
