摘要： A timing signal generator generates a timing signal when an external clock is synchronized with a predetermined internal timing. A frequency-divided clock generator divide a frequency of a DLL (Delay Locked Loop) clock so as to generate an even-numbered divided clock and an odd-numbered divided clock. An even-numbered output enable signal generator generates an even-numbered output enable signal on the basis of an external read command, the timing signal, a CL (CAS Latency), and the even-numbered divided clock. An odd-numbered output enable signal generator generates an odd-numbered output enable signal on the basis of the external read command, a timing signal in which the timing signal is inverted, the CL, and the odd-numbered divided clock. A logical unit logically operates the even-numbered output enable signal and the odd-numbered output enable signal and outputs an output enable signal.

摘要： Disclosed a transmission apparatus in a CDMA mobile communication system. Transmission frames each have a plurality of time slots, and each of the time slots includes two data parts having the same length, a midamble intervening between the data parts, and a guard period for dividing the consecutive time slots. The transmission apparatus modulates the frames into a radio signal with a modulation signal and transmits the modulated radio signal using a plurality of antennas. A power amplifier amplifies the radio signal. A controller generates a switching control signal in a guard period of time slots of a frame associated with the radio signal amplified by the power amplifier. A switch switches the amplified radio signal from the power amplifier between a first and a second antenna in response to the switching control signal.
