Abstract

A method for increasing call access rate in a communication system, which generates a pilot signal from an FPGA (Field Programmable Gate Array) integrated with a multi-carrier digital transceiver, generates a phase-equalized signal from the generated pilot signal a beacon signal; and multiplying the phase-equalized beacon signal by a predetermined oscillation frequency generated by an NCO (Numerically Controlled Oscillator). The NCO output signal and the predistorted user data output signal are summed. The summed signal is reconfigured for synchronization and power amplification.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of earlier filing date and priority of Korean Patent Application No. P2003-92482 filed on December 17, 2003, the contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present invention relates generally to the field of telecommunications, and more particularly to methods and devices for increasing call access rates in communication systems. Background technique [0004] Cellular call handoff refers to the process of transferring a call between base stations. Handoff occurs when a mobile phone user moves between multiple cells and a call is handed off from one cell to another. The mobile services switching center automatically creates and interprets the necessary command signals to control the mobile phone via the associated base station. As a mobile phone user moves from one coverage area to another, the mobile services switching cen...
