1. A method for enhancing the call access rate in a communication system, comprising the steps of:

  • generating a pilot signal from a FPGA (Field Programmable Gate Array) integrated with a multi-carrier digital transceiver;

    producing a phase-equalized beacon signal from said generated pilot signal;

    multiplying said phase-equalized beacon signal by a predetermined oscillation frequency generated by a NCO (Numerical Control Oscillator), said NCO producing an output signal;

    summing up said NCO output signal with a pre-distorted user data output signal;

    rearranging said summed up signal for synchronization and power amplification, said amplified signal including said beacon signal;

    delivering a quantized IF (Intermediate Frequency) signal to a notch filter, said quantized IF signal including said beacon signal; and

    using said notch filter to remove said beacon signal from said quantized IF signal.
