Claim Text:
1. A method comprising the steps of: receiving and demodulating one or more Global Positioning System (GPS) modulated signals into a location finding baseband signal and for providing said location finding baseband signal to an interface unit of a mobile Base Station Transceiver Subsystem (BTS) device for location finding, which location finding baseband signal provides location information of the mobile device: receiving and demodulating in said BTS a spread spectrum video modulated signal into a spread spectrum video baseband signal, converting said spread spectrum video baseband signal into an Orthogonal Frequency Division Multiplexed (OFDM) video baseband signal; modulating said OFDM video baseband signal in a modulator into an OFDM video modulated signal and transmitting in said BTS said OFDM video modulated signal; receiving and demodulating in said BTS an OFDM voice modulated signal into an OFDM voice baseband signal, said OFDM voice baseband signal is converted into a spread spectrum voice baseband signal; modulating said spread spectrum voice baseband signal into a modulated spread spectrum voice signal; transmitting said modulated spread spectrum voice signal; processing in said BTS device a photo camera signal into a Code Division Multiple Access (CDMA) baseband signal; incorporating location information from said location finding baseband signal into said CDMA baseband signal, to provide a location based CDMA baseband signal; said location based CDMA digital spread spectrum baseband signal comprises in-phase and quadrature phase cross-correlated Time Constrained (TCS) waveforms and cascaded Long Response (LR) filter filtered baseband signals; and modulating said location based CDMA digital spread spectrum cross-correlated baseband signal in a modulator into a modulated CDMA digital spread spectrum signal and transmitting in said BTS said modulated CDMA digital spread spectrum signal; further comprising in said BTS device a method for modulation of a first Gaussian Minimum Shift Keying (OMSK) transmit filter filtered baseband signal into a first transmit filter filtered modulated GMSK signal, said first transmit filter filtered modulated GMSK signal comprises cross-correlated in-phase and quadrature phase Time Constrained (TCS) waveforms and cascaded Long Response (LR) filter filtered signals, and demodulating a second GMSK modulated signal into a second GMSK receive filter filtered baseband signal, said receive filter is mis-matched to said transmit filter.
