摘要
Abstract
A channel equalization method applied inOrthogonal Frequency Division Multiplexing(OFDM) system is introduced based on coordinate transformation. This method adopts block pilots to estimate channel response firstly; then by means ofCoordinate Rotation Digital Computer(CORDIC) coordinate transformation, the time-selective fading of channel is compensated. Therefore, the adaptability of the communication system can be improved. Meanwhile, by the linearization of CORDIC at frequency domain, it decreases the complexity of traditional methods of channel equalization and makes them easy to be implemented by hardware. Simulation results indicate the effectiveness and adaptability of the method.关键词
