Title:
MESSAGE PASSING ALGORITHM DECODER AND METHODS
Document Type and Number:
WIPO Patent Application WO/2017/152839
Kind Code:
A1
Abstract:
Methods and devices are disclosed for receiving and detecting sparse data sequences using a message passing algorithm (MPA) with early propagation of belief messages. Such data sequences may be used in wireless communications systems supporting multiple access, such as sparse code multiple access (SCMA) systems. The determination and passing of one or more messages for an edge between a function node and a variable node in a factor graph representation of the system may be performed in serial with determined values available early for subsequent computations. The serial computations may be scheduled based on various factors.
