Abstract
System and method for receiving and transmitting one or more signals, for processing and generating signals used in an infrared (IR) system, in a cellular system and in a separate Wi-Fi wireless network. Receiver and demodulator for demodulating and processing a modulated signal for generating from a modulated signal a demodulated processed position finder signal, including Global Positioning System (GPS) position finder processed signal. Processors and selector for selection of processed TDMA, CDMA and OFDM signals and for providing selected TDMA or CDMA or OFDM or IR signal to a transmitter. Processors for providing cross-correlated GSM, or cross-correlated spread spectrum, or cross-correlated Orthogonal Frequency Division Multiplex (OFDM) baseband signals to quadrature modulators for modulation and transmission. System with multiple input multiple output (MIMO) implementations. Transmitters and receivers for Bluetooth systems and barcode reader provided signals. Processors and receivers for processing touch screen generated signals used for IR, OFDM or TDMA or CDMA systems.
