ABSTRACT:
Herein disclosed are a method and an apparatus for transmitting information converted to a spread spectrum signal, the information being coded to form an information signal before being converted to the spread spectrum signal. The spread spectrum signal is produced on the basis of the information signal and a spreading modulation code which is a pattern of frequency hopping or a pseudo-random noise code well known as PN code. The spread spectrum signal is provided with a signal propagation character when the spread spectrum signal is transmitted. The signal propagation character of the spread spectrum signal is varied while the spread spectrum signal is transmitted, thereby making it possible to reduce the influence of fading effects without applying a diversity system to a spread spectrum receiver and accordingly have the spread spectrum receiver decreased in size, weight and cost.
