摘要
为了纠正由传输信道和功率放大器产生的符号间干扰影响,在通信接收机端需要自适应盲均衡器。针对现存自适应均衡器收敛慢,精度低,硬件资源消耗高的缺陷,提出了一种自适应格型均衡器的交织-流水线的实现结构来进行硬件实现,用来弥补这些缺点。相对于传统均衡器,交织-流水线的格型滤波器实现结构方法收敛迅速,有优越的估计精度,同时也能解决工程实现中硬件资源消耗高的问题。
To solve the problem of inter-symbol interference caused by the transmit channel and power am- plifier, an adaptive equalizer is required in the receiver. Since the existing adaptive equalization is slow in converge and estimation accuracy but high in hardware consumption, an interleaved-pipelined lattice ar- chitecture for adaptive Kalman equalization is proposed. Contrast to traditional adaptive equalization, this interleaved-pipelined lattice architecture is fast in converge, excellent in estimation accuracy, and could in addition, solve the problem of consume hardware consumption in engineering implementation.
