无编码的 meaning in English

codeless

Performance simulation of the proposed estimator including mean squares error ( mse ) of channel and uncoded bit error rate ( ber ) have been taken , and the results show the estimator is efficient and very flexible
对信道盲估计的均方误差( mse )和由此算法获得的信道的状态信息，对无编码的ofdm系统进行解一调的误比特率进行了仿真。
Comparing with si ( sin ( x ) / x ) interpolator , cubic interpolator with low pass filter , and winner interpolator in 16qam ofdm system both in mean square error and bit error rate without encoding , the results of the method proposed by this thesis show that the performance is better than si interpolator and cubic interpolator with low pass filter , and close to the winner interpolator but the complexity is much lower than the latter
在16qamofdm系统中，将其与带低通滤波器的si ( sin ( x ) / x )插值法、 cubic插值法和winner插值法进行了信道估计的均方误差和无编码的误比特率的仿真结果进行了比较。结果表明，本方法的估计性能优于si和cubic插值法，接近优化的winner插值法，但其计算复杂度与winner插值法相比却大大降低。
