Multipath interference is one of the most serious problems for mobile receivers. To reduce interferency many methods and systems have been developed. Two most effective methods are space diversity and electrical cancellation of the interference. The latter method needs not only some complex circuitry such as microprocessor but also a relatively long adjusting time. On the other hand space diversity has comparatively simple electrical structure and is easily realized by means of adequate antennas and their control circuits. The problem of space diversity especially for automobile reception is that a large space is required for a good diversity effect. Therefore, these two methods are not suitable for mobile FM receivers.
