摘要： A method for using superposition in transmission of signals. The method may include receiving, at a first user equipment (UE), a product signal from a transmitter, wherein the product signal comprises a product superposition of a first baseband signal with a first encoded message and a first pilot signal configured for receipt by the first UE and a second baseband signal with a second encoded message and a second pilot signal configured for receipt by a second UE. The method may include estimating, by the first UE using the product signal, a first combined product of the second baseband signal and a first channel coefficient matrix intended for the first UE, wherein estimating is based on the first pilot symbol. The method may include decoding, by the first UE using the first combined product, the first encoded message by removing the second baseband signal from the product signal.

摘要： Various examples are provided for coherence diversity. In one example, a method includes receiving a product signal transmitted over a plurality of subcarriers, the product signal including a product superposition of a first baseband signal and a second baseband signal; estimating equivalent channel responses for the plurality of subcarriers based upon the pilot symbol in the number of time slots of the plurality of subcarriers; and decoding the second encoded message based at least in part upon the first baseband signal and the equivalent channel responses. The first baseband signal can include a pilot symbol in a number of time slots of at least a portion of the plurality of subcarriers and a first encoded message in a remaining number of time slots of the plurality of subcarriers, and the second baseband signal can include a second encoded message.
