The invention discloses an online simulation method and device for baseband receiving performance of a communication base station, and relates to the technical field of communication. The method applied to the algorithm simulation server comprises the following steps: generating air interface time domain data passing through an analog channel and corresponding to a first simulation period, and sending the air interface time domain data corresponding to the first simulation period to a target BBU (Base Band Unit), so that under the condition that a detection result corresponding to the first simulation period sent by the target BBU is received, the detection result corresponding to the first simulation period is sent to the target BBU; and generating air interface time domain data passing through the analog channel corresponding to the next simulation period of the first simulation period based on the detection result, and sending the air interface time domain data corresponding to the next simulation period to the target BBU. Therefore, on-line simulation of the baseband receiving performance of the communication base station can be carried out based on the algorithm simulation server and the target BBU in a real environment, a test environment does not need to be built, and manpower and material resources are obviously saved. And in the process, the algorithm simulation server and the target BBU can ensure that the time domains of the algorithm simulation server and the target BBU are the same through an asynchronous processing mode.
