Abstract: A multi-port correlator and a receiver having the same are provided. A multi-port correlator includes an oscillating unit which generates a plurality of oscillating signals having different phases, a combining unit which combines the plurality of oscillating signals respectively with a radio frequency (RF) signal and outputs a plurality of composite signals.

Abstract: A circuit for electro static discharge protection, for solving a problem of conventional art that a degree of integration of the circuit is lowered because a size of chip and a pitch between pads are increased if a high-voltage mos-transistor is used for applying to a high voltage process, comprising: a first pad; a second pad; and a low-voltage nmos-transistor unit connected between the first and second pads, that is, a low-voltage mos-transistor is applied to an electro static discharge protection circuit and a low-voltage mos-transistor which can be used in common is connected to the pads, and thereby, the size of the circuit is reduced to increase a degree of integration and the size of the pad and a pitch between the pads are reduced. Therefore, if the circuit of present invention is applied to a chip having a plurality of pins, then as ize of the chip can be reduced.

Abstract: A method for shedding traffic load in a code division multiple access mobile communication system, the method performing a soft handoff operation using the ratio of the received forward link pilot signal power to the sum of all interference signals power to transfer a portion of traffic load in the present serving cell with a high traffic density to an adjacent cell with a low traffic density. When the amount of traffic load in the present serving cell is increased and thus exceeds a link capacity of the present serving cell, handoff parameters of all mobile stations in the present serving cell can be updated on the basis of a power allocation state managed by a base station without reducing the coverage of a forward link.
