摘要： A device for rapidly performing initial acquisition and frame synchronization of a received signal for a receiver in a CDMA communication system. To this end, the base station multiplies a spreading sequence for a pilot channel by a synchronization pattern which maintains a pattern of inverting its sign in order to delineate the boundaries of the short sequence periods. A mobile station initially calculates the spreading sequence of the short period and the correlation value to perform initial acquisition, and despreads N-chip duration around a boundary of the one short spreading sequence period to detect the multiplied pattern, thereby acquiring synchronization of a data frame.

摘要： A device and method for controlling communication on a reverse link in a mobile communication system includes a measurer, a controller, and a reverse link transmitter according to an embodiment of the present invention. The measurer detects a power control bit from a channel signal received on a forward link and measures the reception strength of the channel signal using the detected power control bit. The controller compares the reception strength with a threshold and generates a signal for controlling transmission on a reverse link if the channel status of the forward link is determined to be bad during the comparison. The reverse link transmitter stops channel transmission on the reverse link in response to the transmission control signal.

摘要： A mobile station transmits a pilot signal, a common channel signal and a traffic channel signal for a reverse link. The mobile station normally transmits the common channel signal and the pilot signal at a predetermined transmission power, and transmits the pilot signal at a transmission power higher than the predetermined transmission power over a predetermined duration. The pilot signal transmitted over the predetermined duration is spread with a first spreading code over the duration where the pilot signal is transmitted at the predetermined transmission power, and is spread with a second spreading code over the duration where the pilot signal is transmitted at the transmission power higher than the predetermined transmission power.
