DISTRIBUTED CYCLIC DELAY DIVERSITY SCHEME WITH UNIQUE WORD IDENTIFICATION

摘要

Systems and methods for a communication system including a set of transmitters, wherein operations of the set of transmitters are synchronized with an accuracy bound by a synchronization error. A controller forms a message with ordered symbols including data symbols and at least one identification symbol, and controls transmitters from the set of transmitters to transmit the message using a cyclic delay diversity (CDD). Wherein each transmitting transmitter prior to transmitting, circularly rotates the ordered symbols of the message with a unique shift, then copies some symbols located at an end of the message. Wherein a number of the copied symbols is based on a predetermined cyclic prefix length, into a first position in the rotated message, to form a transmitter identifiable message, and transmits via each transmitting transmitter the transmitter identifiable message.
