摘要
针对多载波CDMA通信的部分子载波存在深度衰落的情况,提出子载波选择的通信方法,抛弃处于深度衰落的子载波,选择较好的子载波来进行信息传输。在发射端采用相同的功率情况下,子载波选择的方法比采用全部载波传输的方法有更高的信噪比和更低的误码率。
Aim at partly sub-carder has deeply fading in MC-CDMA communication,proposed sub-carder selection way,abandom the sub-carders in deeply fading,select the sub-carder have well performance to communication. Transmitted the same power,the way of sub-carder selection have even better SNR and lower BER than using all sub-carder.
