摘要
Prior art analog solutions to MIMO detection have the drawback that the number of transistors used increases exponentially in proportion to the number of receiver channels. The current invention aims to find a lower complexity solution to analog equalisation for applications such as MIMO detection and mass storage readers. The analog equaliser includes at least one analogue processing block (APB) arranged in operation to iteratively generate an estimate of marginal posterior expectations for received bit values. A further independent claim states that the equalisation method comprises the step of passing a plurality of log-likelihood marginal posterior expectations to an APB and generating in the APB a revised estimate of the log-likelihood marginal posterior expectations using coordinate descent optimisation.
