Abstract:
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.

Abstract:
On a transmission side, a spectrum- spread spread modulating signal is multiplexed with a spectrum-not-spread information modulating signal in the same frequency band, and, on a reception side, a spread-spectrum demodulating unit (1803) demodulates the spread modulating signal. Then, a spread-spectrum modulating signal reproducing unit (1805) generates a replica signal of the spread modulating signal and a subtraction unit (1807) removes the replica signal from a multiplexed signal to thereby extract an information signal not spectrum-spread. Accordingly, even when many information signals are transmitted in the same frequency band, they can be satisfactorily separated and demodulated on the reception side.

Abstract:
Mobile Networks using Orthogonal Frequency Division Multiplex (OFDM) and or spread spectrum modulation and demodulation techniques process in mobile devices spread spectrum signals into OFDM signals. A first mobile device receives and demodulates a spread spectrum modulated signal into a baseband spread spectrum signal and processes the baseband spread spectrum signal into a first OFDM signal. The first OFDM signal is transmitted to a second mobile device. In the second mobile device the received first OFDM signal is demodulated and processed into a second OFDM signal. The second OFDM signal is transmitted in the mobile network. Alternatively, the first mobile device receives, instead of a spread spectrum signal a modulated OFDM signal. The mobile device has a motion detector which generates a motion detector signal for control of the mobile device. The mobile device has a heart rate sensor and measures the heart rate.
