Patent Searching and Data


Title:
RADIO RECEIVER
Document Type and Number:
WIPO Patent Application WO/2019/137794
Kind Code:
A1
Abstract:
An initial instance of a plurality of data symbols is received (102) and a soft decision for each received data symbol is determined. A scaling factor,inversely proportional to a mean of the absolute values of the initial soft decisions, is calculated (104) and a normalised set of the initial soft decisions is generated (106) by multiplying the soft decisions by the scaling factor.The normalised set and the scaling factor are then stored (108) in memory. If (110) a further instance of the plurality of data symbols is received (114), a soft decision for each newly received data symbol is determined. The stored normalised set is read and denormalised (116) by multiplying the normalised set by an inverse of the scaling factor and the further soft decisions are added (118) to the denormalised set. Anew scaling factor is calculated (120) and the combined set is renormalised and stored in memory (122).
