the paper introduces long curtate new unequal ofdm system.adopts long curtate unequal benefit to be not to require that the second order adding the circulation prefix,being therefore likely to lead into period stationarity,making use of signal therefore in launching an array,counting characteristic property realizing blind estimation of route.this technology includes three kinds of method : subspace decomposition,correlation matching,and maximum likeewise,monte carlo simulation show that whentheeb/no is low,function is better than the other kinds of method.

摘 要：提出一种采用不等长分组新的ofdm系统。采用不等长分组的好处是不需要加循环前缀就能在发射序列中引入周期平稳性，因此，可利用信号的二阶统计特性实现信道盲估计。信道盲估计主要分子空间分解、相关拟合和最大似然三种方法。结合monte carlo仿真表明，在信噪比较低时，结合子空间分解方法计算出的误码性能比其余两种方法好。
