In a radio network that includes at least one base station and at least one remote station, signals are modulated for transmission from the remote stations by embedding known information throughout the signal in a predetermined pattern and a group of sample vectors of a signal received by at least one base station of the network are collected and processed to detect a said received signal that resulted from propagation of a signal from a remote station of the network. The group of sample vectors is collected from (a) signals that are received by more than one base station of the network; and/or (b) signals that are received simultaneously at different frequencies by at least one base station of the network.

Detection of signals in a radio network

Family of methods for correcting errors in transfer of information over a lossy medium. The message to be sent is first broken into Data Blocks, which are further divided into N data segments. These data segments are sent verbatim and followed by XOR combinations of the data segments, called Error Correcting Segments. Incorrect Data or Error Correcting Segments are detected through the use of a CRC or any other error detection algorithm, and errored Data or Error Correcting Segments are discarded. Once all Data or Error Correcting Segments for a message segment are received, logic or a look up table is used to determine which of the Data Segments can be recovered. The lost Data Segment recovery is done using a binary XOR of multiple good Data or Error Correcting Segments. For additional error correction, Data and Error Correcting Segments can also be repeatedly transmitted multiple times to further improve the performance of this algorithm.
