Global Positioning System (GPS) and non GPS position finder, emergency,
multiple input multiple output (MIMO), multimode, spread spectrum, code
division multiple access (CDMA), Global Mobile System or Global System
Mobile (GSM) and orthogonal frequency division multiplex (OFDM)
communication systems. Position finder and emergency communication
multiple input multiple output (MIMO) system and a receiver having
multiple inputs for reception and demodulation of position finder signals
to position finder baseband signals. A processor for processing position
finder signals with a signal containing an emergency number. A processors
for processing signals to provide cross-correlated shaped in-phase and
quadrature-phase baseband signals, spread spectrum and OFDM baseband
signals. A control unit for control and selection of one of the jointly
processed signals and a selector for providing the selected signal to a
modulator. A modulator for modulating the selected signal and for
connecting the modulated signal to a multiple output signal transmitter
for signal transmission.A demodulator connected to the emergency receiver
for demodulation of the modulation format selectable (MFS) and bit rate
agile (BRA) modulated signal with at least one demodulator filter which
has a mis-match with the corresponding filter of the modulator.
