Abstract: A method and system for canonical channel estimation in the Long Term Evolution uplink where a multi-frequency signal is generated and then converted to frequency spectrum which is then convolved in the frequency domain with a truncated window function to obtain a time domain channel impulse response. The time domain channel impulse response can be then transformed to a frequency domain to produce a down sampled user channel response, which can be then linearly interpolated to provide a channel estimate for a plurality of subcarriers. Such an approach achieves channel estimation within Long Term Evolution at only canonical locations to reduce complexity without loss in channel entropy.

Abstract translation: 一种用于在长期演进上行链路中进行规范信道估计的方法和系统，其中生成多频信号，然后将其转换为频谱，然后将频谱卷积在具有截断窗函数的频域中以获得时域信道脉冲响应。 然后可以将时域信道脉冲响应变换到频域以产生下采样的用户信道响应，然后可以对其进行线性内插以提供多个子载波的信道估计。 这种方法在长期演进中仅在规范位置实现信道估计，以减少复杂度而不损失信道熵。
