    Abstract: A CDMA communication system includes a signal processor which encodes voice and nonvoice signals into data at various rates, e.g. data rates of 8 kbps, 16 kbps, 32 kbps, or 64 kbps as I and Q signals. The signal processor selects a specific data rate depending upon the type of signal, or in response to a set data rate. When the signal is received and demodulated, the baseband signal is at the chip level. Both the I and Q components of the signal are despread using the conjugate of the pn sequence used during spreading, returning the signal to the symbol level. Carrier offset correction is performed at the symbol level. A lower overall processing speed is therefore required.

    Abstract: The present invention is a method and apparatus for reducing transmission errors by a user equipment (UE) when transmitting a communication signal. An RF communication signal is received at the UE and analyzed for errors. A correction signal is then generated based upon the analysis. Prior to transmission of the communication signal from the UE, the communication signal is corrected using the correction signal.

    Abstract: A modulator capable of providing a fractional sample or symbol 995486 time employs a decimation counter (23) responsive to a clock having a frequency equal to M/N.times.(data symbol clock), where M is an interpolation factor and N is a decimation factor, for generating a data symbol clock to select FSK symbols from a sampled data array (21). A multiplier (26) receives the FSK symbols and multiplies the symbols by a weighting factor determined by the decimation counter. When the decimation counter wraps around due to a modulo M operation, a fractional weight is calculated for the current FSK symbol, then a new FSK symbol is selected, and then a fractional weight is calculated for the new FSK symbol. When the decimation counter has not wrapped, the full weighting, N, is output for the current FSK symbol.

    Abstract: A spatial diversity system for digital mobile telephone networks which comprises at least two antennas, one antenna being part of a primary (or master) unit and the other being part of a diversity (or slave) unit, each unit having processing means to detect the "quality" of digital audio signals received by their respective antennas, the "quality" comprising link quality, AGC level and parity errors; the primary unit being capable of comparing the "quality" of the audio signals received by each antenna, selecting the higher "quality" signal and transmitting the higher "quality" signal to the telephone network.

    Abstract: A decoder decodes a plurality of received convolutionally encoded date signals simultaneously. At least two of the encoded data signals have a different data rate. The decoder receives undecoded I and Q symbols from the plurality of encoded data signals and outputs Euclidian distances corresponding to each encoded signal. Each data signal's distances are mapped on to a trellis. To output decoded symbols of each data signal, decisions are traced back in each data signal's trellis.
