摘要: Error correction techniques based on a modified chase combining (MCC) in data retransmission in communication systems such as wired and wireless communication systems. The described MCC may be implemented in wireless communication systems that use hybrid automatic repeat request (H-ARQ) in data transmission. In wireless systems, the mobile communications devices and base stations may be designed with the present MCC.

摘要: A method and apparatus for collecting and broadcasting vehicular traffic in a summarized and compressed format suitable for reception by inexpensive wireless devices. In the preferred embodiment, vehicular traffic data is received from one to many inexpensive Doppler Sensors mounted in fixed locations reflecting the speed of vehicles entering one or more known spatial points. In the preferred embodiment of the invention, the averaged vehicle speed is encoded in a compressed, quantized format and formed into a broadcast unit containing data from multiple locations. The broadcast unit is then broadcast over a cellular (e.g. CDMA) network for reception by inexpensive wireless devices. The wireless devices can then use the data to display traffic data in a graphical format or be processed for route planning or other similar functions.
