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: 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: 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: The present invention is directed to a digital wireless telecommunications system that includes a plurality of base station of differing spectral capabilities, and a plurality of remote stations capable of transmitting data to and receiving transmissions from the plurality of base stations. The invention herein provides a method for remote station hand-off between base stations of a narrower spectral capacity and base stations of a wider spectral capacity. A method is provided for a wireless telecommunications infrastructure to facilitate a remote station hand-off from a set of narrowband compliant base stations to at least one wideband compliant base station while a remote station is in the coverage area of both types of base stations. Additionally, the invention herein provides remote station apparatus, base station apparatus, and base station controller apparatus for performing the handoff methodology of the present invention.
