Fig. 3From: Jointly optimized design of distributed RS-coded spatial modulation by appropriate selection at the relayInformation sequence with more symbols in a first part, b last part. For information sequence with length \(K_1\) at the source node, its symbols are divided into two cases. One case is the first part has more symbols, and the other case is the last part has more symbols. a denotes the symbol distribution diagram of information sequence with more symbols in the first part. b denotes the symbol distribution diagram of information sequence with more symbols in the last partBack to article page
