一種基站，包含記憶體、處理器、射頻電路與輸出輸入電路。處理器耦接於記憶體，用以讀取至少一電腦程式以執行多個操作，包含：產生實體層的數位訊號；估算取樣參數值以及插入參數值；依據取樣參數值以及插入參數值對實體層的數位訊號執行內差有限脈波響應濾波處理以產生第一子訊號。射頻電路用以依據遮罩濾波截止頻率對第一子訊號進行遮罩濾波處理，以產生第二子訊號，並將第二子訊號轉換為類比訊號，並依據類比訊號產生輸出訊號。輸出輸入電路用以傳送輸出訊號。

A base station includes a memory, a processor, a radio frequency circuit, and an input and output circuit. The processor is coupled to the memory for reading at least one computer program to perform several operations, including: generating digital signals at the physical layer; estimating a sampling parameter value and an inserting parameter value; performing an interpolation finite impulse response filter process to the digital signal of the physical layer according to the sampling parameter value and the inserting parameter value to generate a first sub signal. The radio frequency circuit is configured to perform a masking filter process according to a masking filter cutoff frequency to the first sub signal to generate a second sub signal, to convert the second sub signal into an analog signal, and to generate an output signal according to the analog signal. The input and output circuit is configured to transmit the output signal.
