Abstract: Systems and methods for interleaver and deinterleaver memory partitioning optimize data rate and error correction. Optimized memory allocation is important in systems that support bi-directional communication over multiple data paths. By using path-specific information such as impulse noise protection and data rate, memory may be dynamically partitioned to optimize the capacity in individual data paths.

Abstract: A method and apparatus for transmitting and receiving data, wherein a narrow band data signal is transmitted at an unknown frequency within a known range of frequencies and received, and, at the receiver, the range of frequencies is divided into plural frequency bands each of width less than the uncertainty in the transmission frequency of the data signal, with the presence of said data signal detected in at least one of said frequency bands and thereupon demodulated.

Abstract: A computer-implemented method manages the execution of one or more processes within a processing period, each process having a completion priority. The method includes determining an interval based on the number of processes currently executing on a processor; executing the one or more processes during the interval; upon reaching the end of the interval, determining a remaining processing time associated with one or more remaining processes; and if the remaining processing time exceeds the difference between the processing period and the interval, terminating one or more remaining processes based on the completion priority of each process.

Abstract: A method to separate data transmitted in parallel at arbitrary frequencies within a channel includes: separating a signal from one channel into a plurality of bins representing sub-channels, each bin having a bin frequency; generating a locked frequency by applying a phase locked loop (PLL) to each sub-channel; determining a difference between the locked frequency and the bin frequency; and correlating the signal with a difference between the locked frequency and the bin frequency.

Abstract: A receiver which is capable of receiving in parallel data transmitted at arbitrary frequencies within a radio channel includes: a radio frequency (RF) front end to convert an RF signal to a digitized signal; a Fast Fourier Transform (FFT) generator coupled to the RF front-end to separate the digitized signal into a plurality of sub-channels; a bank of phase locked loops (PLLs) coupled to the FFT generator, each PLL operating on a sub-channel with a sub-channel center; and a flag detector coupled to the bank of PLLs to detect variations from the sub-channel center and to recover the usage data transmitted from the end-point.

Abstract: A remote data collection system for collecting usage data from an endpoint includes a monitoring module coupled to the endpoint, the monitoring module having a wireless transmitter to transmit the usage data. The system also includes a receiver to receive usage data from the wireless transmitter of the monitoring module, the receiver capable of receiving in parallel data transmitted at arbitrary frequencies within a radio channel.
