摘要

正交频分复用(OFDM)是一种很有前途的适合于高数据速率无线通信系统的调制技术。OFDM是适合多径通信信道和衰落环境的最有效的调制技术。然而，在OFDM系统中，错误控制编码(ECC)的存在是保证数据可靠传输的必要条件。这是由于ECC可以检测和纠正接收到的数据的能力。本文研究了汉明码和卷积码两种ECC的性能。介绍了仿真系统和参数，并对仿真结果进行了讨论。

BER performance of OFDM system with the effect of error control code

Orthogonal Frequency Division Multiplexing (OFDM) is one of the promising modulation techniques suitable for high data rates in a wireless communication system. OFDM is the most effective modulation technique suitable for multipath communication channel and fading environment at reasonable complexity. However, the existence of Error Control Coding (ECC) in OFDM system is necessary for the reliable data transmission. This is due to the capability of ECC which can detect and correct the data received. Two types of ECC performance which are Hamming code and convolutional code are investigated in this paper. The simulation system and parameter are described and the results are discussed.
