Abstract

Simulation of the Herault-Jutten (H-J) algorithm and its hardware implementation are discussed. Since the algorithm is general and realizable in hardware, numerous applications exist. Results shown that the circuit is effective for channel separation and works very well for separating individual speech from mixed-speech signals, i.e. speech enhancement in a multispeaker environment. When signals received from multiple sensors are mixed in an unknown manner because the sensors are dependent on more than one variable, the H-J algorithm is capable of separating them into the original uncorrupted signals for both linear and nonlinear mixing.<>

自适应模拟电路执行多维传感器信号的信号分离

讨论了Herault-Jutten (H-J)算法的仿真及其硬件实现。由于该算法具有通用性，可在硬件上实现，因此存在大量的应用。结果表明，该电路可以有效地进行信道分离，并且可以很好地将单个语音从混合语音信号中分离出来，即在多扬声器环境中进行语音增强。当从多个传感器接收到的信号以未知的方式混合时，因为传感器依赖于多个变量，H-J算法能够将它们分离成原始的未损坏信号，用于线性和非线性混合。
