Abstract: 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.

Abstract: A method and apparatus are disclosed for wirelessly communicating signals from trailer-mounted cameras to a towing vehicle, where the techniques overcome packet loss challenges caused by interferences, fading and poor signal strength. An advanced spectrum hopping algorithm monitors conditions on multiple channels in multiple frequency bands, detects congestion or collisions needing mitigation, and migrates transmissions as needed to other channels with greater free capacity. Network coding techniques are provided which transmit data packets via multiple paths, where the redundancy provides robustness against data packet losses. The multiple path network coding approach may include spectral diversity, where packets are transmitted on different bands, and spatial diversity, where packets are transmitted via different routes such as direct and repeater-based.
