Abstract: A method for demodulating a received signal comprising complex multiplying (202,204) the received signal by a complex pseudonoise code to produce a complex pseudonoise despread signal (XI,XQ); filtering (214) the complex pseudonoise despread signal to provide a complex filtered pilot signal; multiplying (210) the complex pseudo-noise despread signal by a first demodulation code to provide a first complex demodulated data signal; and phase rotating and scaling (216,218) the first complex demodulated clara signal in accordance with the complex-filtered pilot signal to provide a first soft decision data.

Abstract: A wireless transmitter comprising an encoder for encoding a set of information bits to provide a set of code symbols at a data rate. A demultiplexer provides the set of code symbols in first and second code symbol subsets, each having different code symbol rates, to first and second modulators, wherein the data rate is equal to a combination of the different code symbol rates. The first and second modulators respectively modulate the first and second code symbol subsets according to first and second code symbol rate formats, respectively, wherein the different code symbol rates have a ratio equal to a number other than one, to provide a modulated first code symbol subset and a second code symbol subset. A transmission subsystem provides the modulated first code symbol subset on a first carrier frequency and the modulated second code symbol subset on a second carrier frequency.

Abstract: Apparatus and method for use in a mobile station in a wireless communication system, comprising in which: a decoder (218) detects if frames received from a base station are good or bad; a first counter (224) counts received bad frames; a second counter (226) counts received good frames; a control processor for resets the first counter (224) to zero and incrementing the second counter (226) by one if a received frame is declared a good frame, and incremens the first counter (224) by one and resetting the second counter (226) to zero if a received frame is declared a bad frame, and disables a transmitter if the value of the first counter (224) reaches a predetermined threshold.

Abstract: A method and apparatus for transmitting broadcast information in a multi-carrier communication system. The Sync Channel of the multi-carrier system is transmitted a 1.25 MHz channel bandwidth (i.e., over a single carrier), and to specify the preferred channels for the Sync Channel transmission instead of the preferred channels for the entire multi-carrier system. The Sync Channel Message will carry the additional information to indicating the center frequency of a multi-carrier system within a reserved set of frequency bands and indicating the frequency of a single carrier system in the reserved set of frequency bands. Considering the A block of the PCS band again, the preferred channels for Sync Channel transmission can be selected as channels 75, 150 and 225. This selection ensures that one of the preferred channels will always be used by any multi-carrier system regardless of the location of its center channel.
