1. A wireless mobile system with beam-steering phased array antennas, the wireless mobile system comprising:

  • at least one or more phased array antennas, each phased array antenna comprising an array [N×

    N] of radiating elements;

    at least one DSP Phase Processor for calculating desired phase shift values to achieve transmit wave lobe steering angle θ

    for controlling phased shifters associated with each radiating elements;

    at least one or more Phase Shifters associated with each radiating elements adapted to receive transmit signals, wherein each phase shifter varies the phase of the transmit signals before feeding to the radiating elements;

    at least one or more base station trackers associated with each radiating elements adapted to receive signals, each base station tracker determining the current location of the communicating base station;

    at least one or Signal Feed Processor for distributing the transmit signals to each radiating elements;

    at least one Transmitter adapted to receive OFDM signals for further modulating and wave shaping the signals before sending to the radiating elements;

    at least one or more Transmit Baseband Processors adapted to received digital information data for transmitting, wherein each Transmit Base Processor comprises;

    at least one inverse Fast Fourier Transform (iFFT) module adapted to receive encoded data sequences for modulating the data into multiple Orthogonal frequency-division multiplexing (OFDM) signals before feeding to the Transmitter; and

    at least one Turbo Codes Encoder module adapted to receive data for encoding input information into encoded data sequences with parity bits for error-correction before feeding to the iFFT module;

    at least one Clock Management Logic for controlling the clock distributions to the target modules; and

    at least one Power Management Logic for controlling the power distributions to the target modules.
