Current and future vehicles are rapidly increasing the interaction with the environment. Active safety systems sense other road users and support the driver by warning and emergency interventions. Vehicles are responding to information from the road network infrastructure and also assist in post crash situations by transmitting the vehicle position to the emergency centre. In the not too distant future...
The multiple input multiple output (MIMO) system can be considered a solution which is efficient for the wireless communication requiring high speed. But due to dealay spread in non-flat fading channels abrupt the functioning of MIMO system. The impulse response of the channel in orthogonal frequency division multiplexing (OFDM), is flat in each sub carrier. Hence, MIMO with OFDM can be used effectively...
Communication circuits/systems suffer from design margins required to support wide channel variations, increasing manufacturing process variations and multi-standard operation. Recent advances in channel and process adaptive communication systems, enabling zero-margin power-efficient operation and adaptive variation-tolerant self-healing systems enabling yield improvement are discussed.
