In recent years, the number of portable mobile terminal users is increasing with improvement of the wireless communication environment. In addition, mobile multimedia services also bring the increase of wireless traffic and lack of spectrum resources. As a technique for efficient spectrum use, spectrum sharing receives much attention. It dynamically assigns a spectrum channel from a larger area network such as WiMAX to smaller area networks such as WiFi-based wireless LANs and achieves to increase the total wireless communication capacity of this area. In a case where all providers are cooperative, the spectrum sharing can be realized easily and improve user throughput in average. In another case where providers are not cooperative, some spectrum trading methods based on auction theory had been proposed.

PCM文件采样率转换，其中可以自己定义采样率。作为WAV文件进行存储。效果较好。注意使用时确定源文件采样率。(PCM file sample rate conversion, which could define their own sampling rate. As a WAV file is stored. Effective. Note that when used to determine the source file sample rate.)
