Abstract

Video and data cross-correlated in-phase and quadrature-phase processed and filtered baseband signals and location finder signals are quadrature modulated and transmitted in systems having two or more than two antennas. Signals used in Wi-Fi networks using Orthogonal Frequency Division Multiplexed (OFDM) modulated signals are also transmitted in the two or more than two antenna transmit system. Data and OFDM signal is used in a Voice over Internet Protocol (VoIP) or Video over Internet Protocol (ViIP) network and video cross-correlated modulated signal is used in ViIP wireless networks and in cellular systems.

Claims

1. A system comprising:

a processor and filter for receiving, processing and filtering a received location finder signal and for providing processed location finder and a processed video cross-correlated in-phase and quadrature-phase filtered baseband signal to a quadrature modulator for quadrature modulation of said processed cross-correlated baseband signal;

a processor for processing a data signal and for providing a processed data signal to Wi-Fi modulator for modulation of said processed data signal; and
