Abstract
A processor-implemented method by a message recipient in a vehicle or on a mobile device for decoding overlapping wireless messages is provided. The method comprises: receiving a first message from a first message sender that overlaps with a second message received from a second message sender; estimating, in a first signal recovery phase, a received data symbol (d0) from the first message and a channel impulse response (h1) corresponding to a data channel between the message recipient and the second message sender; estimating, in a second signal recovery phase, a received data symbol (d0)′ from the first message and a received data symbol (d1) from the second message; and reconstructing the first message from the estimated data symbol (d0) estimated in the first signal recovery phase and estimated data symbol (d0)′ estimated during the second signal recovery phase and reconstructing the second message from the estimated data symbol (d1) estimated during the second signal recovery phase.
