Abstract
A method and system is disclosed for transmitting signals at particular angles (i.e. angular hopping) thereby decreasing the amount of signals transmitted at angles that result in signals, or instances thereof, being received by a receiver with poor channel conditions. Wireless signals may be transmitted at angles that are randomly selected over time or varied over time according to a predetermined amount. Additionally, where feedback information is provided from a receiver to a transmitter, signals may be transmitted at angles where a receiver has indicated that signals are being received with good channel conditions.
