In the second part , introduces the theory of wireless lan based on the ofdm , supplies the corresponding simulation analysis by systemview software , compares two channel coding by simulatation , gives a advice to use convolution coding , and analyses its ber
第二部分通過分析無線局域網(wǎng)的基本原理，以及采用仿真軟件分析了ofdm在無線局域網(wǎng)中的應(yīng)用。通過仿真比較了兩種信道編碼的性能，并做了相應(yīng)的誤碼率分析，得到了有用的結(jié)論。建議采用卷積編碼。
