A method and apparatus for enhancing the call access rate in a communication system generates a pilot signal from a FPGA (Field Programmable Gate Array) integrated with a multi-carrier digital transceiver, produces a phase-equalized beacon signal from said generated pilot signal, and multiplies the phase-equalized beacon signal by a predetermined oscillation frequency generated by a NCO (Numerical Control Oscillator). The NCO output is summed up with a pre-distorted user data output signal. The summed up signal is rearranged for synchronization and power amplification.
