<p>PROBLEM TO BE SOLVED: To efficiently utilize a usable band, which is to be changed with the time of an RE channel, and to be flexibly adaptive to it by reprogramming and rearranging (reconfiguring) at least one programmable device. SOLUTION: A system performance measuring and optimizing (SPM/O) block 110 is arranged inside a reception chain 124. The SPM/O 110 monitors the performance of a channel 105, digital demodulator 106, channel decoder 107 and source decoder 108. Then, it is determined as needed which one of blocks 102-104 in a transmission chain 128 and which one of blocks 106-108 in the reception chain 124 are to be dynamically reconfigured. When reprogramming is required, the SPM/O 110 instructs the reprogramming of the programmable device to a programming logic 22.</p> |
