Abstract
Barcode reader, location finder, Global Positioning System (GPS), navigational interactive Time Division Multiple Access (TDMA), Global Mobile System (GSM), spread spectrum Code Division Multiple Access (CDMA) wireless and wired communication systems. Processors and readers for processing and reading barcode signals, location finder and user signals. Processed and filtered cross-correlated in-phase and quadrature-phase filtered signals and processed Orthogonal Frequency Division Multiplex (OFDM) or Orthogonal Frequency Division Multiple Access (OFDMA) filtered signals. Quadrature and polar modulated signals provided for signal transmission and reception. Receiver for reception of transmitted signal with a filter which is mis-matched to the filter used for processing and filtering cross-correlated in-phase and quadrature-phase filtered signal. Processed cross-correlated in-phase and quadrature-phase filtered signal with Time Constrained (TCS) waveform and cascaded Long Response (LR) filtered signals.
