A processor-implemented method and a controller in a vehicle for estimating a wireless channel impulse response in a mobile environment are provided. The method comprises: receiving an orthogonal frequency-division multiplexing (OFDM) signal; applying a maximum likelihood estimator to the received OFDM signal to identify a data symbol that provides a smooth channel response; and estimating the channel impulse response by performing a division or reverse convolution operation between the received OFDM signal and the identified data symbol. The controller is configured to: receive an OFDM signal; apply a maximum likelihood estimator to the received OFDM signal to identify a data symbol that provides a smooth channel response; and estimate the channel impulse response by performing a division or reverse convolution operation between the received OFDM signal and the identified data symbol. The vehicle can use the estimated channel impulse response to decode data symbols from future instances of the OFDM signal.

Low-complexity channel estimator for OFDM receivers

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 (d) from the first message and a channel impulse response (h) 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 (d)' from the first message and a received data symbol (d) from the second message; and reconstructing the first message from the estimated data symbol (d) estimated in the first signal recovery phase and estimated data symbol (d)&#x2032; estimated during the second signal recovery phase and reconstructing the second message from the estimated data symbol (d) estimated during the second signal recovery phase.

Technical solutions are described for facilitating intra-vehicle wireless communication among a plurality of electronic control units. An example method includes determining, by a first electronic control unit in a vehicle, a wait-time for a message, which is to be transmitted to a second electronic control unit in the vehicle via a wireless channel. The first electronic control unit executes a first availability-check, by determining availability of the wireless channel. In response to the first availability-check indicating that the wireless communication channel is available, the method includes delaying transmission of the message by the wait-time.
