FLUCTUATING TRANSMISSION DIRECTIONAL PATTERN FOR SUPPORTING SIGNAL PICKUP IN RECEIVER

摘要

FIELD: physics. ^ SUBSTANCE: communication system has a stationary transmitter and a mobile wireless communication device. The stationary transmitter transmits a source signal defined by a set of symbols. At least one of the symbols in the set is transmitted with a unique power level so that the transmitted source signal is detected with the linearly independent time periods of the power level. The linearly independent time periods of the power level are used by the mobile wireless communication device to populate a mixing matrix for processing in order to pick up the signal. ^ EFFECT: high noise immunity when receiving and picking up signals. ^ 38 cl, 23 dwg
