WiMAX和WiBro结构中高数据率调制的使用要求传输信号的低失真和低相位误差。WiMAX应用主要面向2.5GHz和3.5GHz频带,而WiBro作为相关的韩国无线宽带技术则指向2.3GHz~2.4GHz频带。
The use of high data rate modulation in WiMAX and WiBro architectures requires low distortion and low phase errors in the transmitted signal. WiMAX applications mainly for the 2.5GHz and 3.5GHz bands, while WiBro as the relevant Korean wireless broadband technology points to the 2.3GHz ~ 2.4GHz band.
