1. A spread spectrum base station comprising:
- means for generating a plurality of spread spectrum signals, the spread spectrum signals encompassing a selected frequency spectrum;
means for detecting frequencies within the selected frequency spectrum by a microwave power associated with the detected frequencies;
means for notch filtering the spread spectrum signals so that a transmitted version of the spread spectrum signals is notch filtered at the detected frequencies; and
means for transmitting the notch filtered spread spectrum signals.

Abstract
A spread spectrum base station generates a plurality of spread spectrum signals. The spread spectrum signals encompass a selected frequency spectrum. Frequencies within the selected frequency spectrum having a high microwave power are detected. The spread spectrum signals are notch filtered at the detected frequencies. The notch filtered spread spectrum signals are transmitted.
