OFDM Mobile Networks

摘要

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.

主权项

1. A method comprising steps of:
receiving, demodulating and processing, in a first mobile device, a spread spectrum modulated signal into a first baseband signal; storing, or processing said first baseband signal in said first mobile device into a processed first Orthogonal Frequency Division Multiplex (OFDM) signal; modulating said first OFDM signal into a first OFDM modulated signal; transmitting said first OFDM modulated signal; receiving and demodulating, in a second mobile device, said first OFDM modulated transmitted signal into a second baseband signal; storing or processing, in said second mobile device, said second baseband signal into a stored second baseband signal or processing said second baseband signal into a processed second OFDM signal; modulating said second OFDM signal into a second OFDM modulated signal; transmitting said second OFDM modulated signal; and processing in said first mobile device one a touch screen generated signals into a touch screen control signals for control of said first mobile device.
