Abstract: A system and method of recovering symbol timing from a high symbol rate TDD or TDMA broadband transmission. A correlator operating at a fraction of the symbol rate receives in-phase and quadrature data signals from a broadband demodulator and processes those signals using a predefined match filter for a pilot signal to detect the pilot signal. The correlator measures any timing error in the symbol timing and adjusts a pointer in a memory buffer to replay the pilot signal to the correlator. Again, any timing error is determined and the pointer in the memory buffer is adjusted for a final replay of the pilot signal as well as the data to the correlator. At this point the timing error in the symbol timing is reduced to a minimum. With symbol timing established, coefficients in an equalizer are adjusted so that the remaining data transmission is properly received.

Abstract: A dual mode mobile handset provides a single set of RF circuit elements which interface with a single set of analog circuit elements thereby reducing redundancy in the system. A DSP connected to the analog circuit elements modulates and demodulates both modes of transmission signals with software elements and pre and post processes the standard signals employing embedded softward. A single control CPU provides data to and receives data from the DSP for selected processing as the first standard transmission signal or the second standard transmission signal.

Abstract: A Frequency Mapping Coding (FMC) scheme varies the application of error correction redundancy to transmitted data based on the channel transmission characteristics and the likelihood of error resulting from characteristics of the data stream being transmitted over the channel. The FMC is an error correction coding scheme making use of the non-linear feed-back mechanism and variable bit input step size to control redundancy applied. The FMC scheme accommodates the non-symmetrical nature of the SNR in bandwidth limited communications environments such as DSL to allow application of IQ based modulation, such as QAM, to these channels and is flexible for varying channel characteristics.
