The problem of simpler more efficient multimode wireless communication and of location finding in distinct cellular systems and wireless networks is solved by the current multimode wireless invention, having touch screen operation and touch screen generated control and having parts of Bluetooth, Wireless Fidelity (Wi-Fi), third generation (3G) and Global Positioning System (GPS) in a single device, instead of separate devices. A received GPS signal is processed with a Bluetooth signal, or with processed Wi-Fi signal, or with a processed 3G signal and is provided to a transmitter for transmission. Frequency Hopped Spread Spectrum (FH-SS) signal is processed with a frequency division multiplexed (OFDM) signal and or with time division multiple access (TDMA) or Code Division Multiple Access (CDMA) signals. Filtered and shaped cross-correlated in-phase and quadrature-phase baseband signals are generated. TDMA systems include Global Mobile System (GSM) implementations. Processing and providing processed position finder signal received from at least one satellite transmitter and from at least one land based transmitter. Demodulating and processing of a modulated transmitted signal, with demodulation and post demodulation filtering by a filter which is mis-matched to the corresponding transmit filter. |
