ABSTRACT:
In a communication system10,a method and apparatus provide for decoding a sequence of turbo encoded data symbols. The channel nodes Rx, Ryand Rzare updated based on a received channel output, and the outgoing messages from symbol nodes (701, 707, 708) are initialized. The symbol nodes symbol nodes (701, 707, 708) are in communication with the channel nodes Rx, Ryand Rz. Updates of computational nodes C (704) and D (706) at different time instances are performed in accordance with a triggering schedule.
