<p>PURPOSE:To transmit a received burst signal efficiently by transmitting the received burst signal while expanding the time axis, and compressing the time axis of the received burst signal in a transmitted frame signal after the time axis is expanded. CONSTITUTION:The 1st and the 2nd digital received burst signals from input terminals 10a and 10b are supplied to FIFO memories 12a and 12b as time-axis expanding means through compensating and delaying circuits 11a and 11b. Further, outputs of the FIFO memories 12a and 12b are supplied to signal synthesizing circuits 17a and 17b and a system subframe synchronizing signal and a channel signal, and delay time detection signals from latch circuits 18a and 18b are supplied to digital received burst signals obtained from the FIFO memories 12a and 12b after the time-axis expansion. Then, outputs of signal synthesizing circuits 17a and 17b are multiplexed by a multiplexer 19 and sent out, and the transmitted received burst signal is processed by time-axis compression to obtain the original received burst signals.</p> |
