IPC: H04B7/216

Abstract: PURPOSE: An apparatus for highly searching a cell in a synchronous CDMA communication system and a method thereof are provided to shorten a cell searching time by obtaining a scramble code of a base station at the same time as a frame synchronous signal in case that the cell is searched in the asynchronous CDMA communication system. CONSTITUTION: A matching filter correlates the second synchronous code of the first period with the second period signal of the second synchronous channel, and an accumulator accumulates an output of the matching filter by a slot. A discriminator checks the output of the accumulator, and if the output of the accumulator is larger than a reference energy, outputs "1", and thus finally outputs a scramble code number. A base station transmits the second synchronous channel having the first interval contained in second synchronous code information and transmits the second interval having the second interval consecutive to the first interval and contained scramble code information. A mobile terminal obtains a scramble code number of a base station at the same time as a frame synchronous signal. To obtain the scramble code number, the mobile terminal obtains a scramble group information by using the second synchronous code transmitted during initial 256-chips period, and calculates a corresponding bit of scramble group information by correlating information transmitted during a next 256-chip period with the second synchronous code transmitted during initial 256-chip period.

Abstract: PURPOSE: A display method of variable scaling of electronic map for car navigation is provided to add a digital zoom function for further displaying a variable level between prior fixed level, thereby enhancing the convenience of a driver. CONSTITUTION: The display method of variable scaling of electronic map for car navigation comprises a step preparing a variable reducing/expanding key for variable scaling between fixed scaling levels. Then, a variable level between the fixed levels are decided and then a variable used in transforming a map of a fixed level into a map of the variable level is initialized into 0. Next, the scale of a current level is decided by deciding a current fixed level and then the scale of the next level is decided. Then, a m_scale used to finding a corresponding level among variable levels between the fixed scales is decided. Next, a variable scale to be displayed is decided and the coordinates of map data of a current scale are converted into those of a map data of a variable scale. Finally, the converted coordinates are displayed on an LCD.
