Provided is a signal generation processing device that achieves audio synthesis processing or image signal generation processing capable of obtaining high-quality audio signals or image signals while maintaining the speed of audio synthesis processing or image signal generation processing. In the signal generation processing device, the first sub-model unit to the N-th sub-model unit each performs training processing for training models included in the first sub-model unit to the Nth sub-model unit using noise levels included in different noise level ranges to obtain trained models. In other words, the signal generation processing device performs processing for each sub-model unit in parallel, thus allowing for performing the training processing at high speed. Further, during prediction processing, the signal generation processing device appropriately selects the sub-model units to be used and performs processing with the selected sub-models, thus allowing for performing audio synthesis processing and image generation processing with high accuracy.

Delay time in a signal transmitted between nodes in daisy chain connection is accurately compensated. A TRX amplifier measures phase difference between a UL frame received from a downstream chain, and a UL frame to be sent out to an upstream chain, and reports the phase difference to a base transceiver station. The base transceiver station calculates advance amount to be set to a downstream TRX amplifier based on the reported phase difference. The TRX amplifier adjusts phase difference between a DL frame received from an upstream chain, and the UL frame to be sent out to the upstream chain depending on the advance amount.
