摘要

本文比较了具有完美信道估计的相干RAKE和差分RAKE接收机的性能。在存在导频信道的前向链路中可以实现完美的信道估计假设。然而，在反向链路中，如果没有导频信道，信道估计的误差会导致理论性能的偏差。提出了一种信道适应的RAKE接收器来最小化这些偏差。

Channel adapted RAKE receiver (CARAKE) for coherent uplink demodulation

The paper presents a comparison of the performance between coherent RAKE and differential RAKE receivers with perfect channel estimation. The perfect channel estimation assumption can be realised in the forward link where there is a pilot channel. In the reverse link however, where there is no pilot channel, errors in channel estimation lead to deviations from the theoretical performance. A channel adapted RAKE receiver is proposed to minimise these deviations.
