Fig. 4From: Jointly optimized design of distributed RS-coded spatial modulation by appropriate selection at the relayInformation sequence with 7 symbols in a first part, b last part. For information sequence with length \(K_1=13\) at the source node, its symbols are divided into two cases. One case is the first part has more symbols (7 symbols), and the other case is that the last part has more symbols (7 symbols). a denotes the symbol diagram of information sequence with more symbols (7 symbols) in the first part. b denotes the symbol diagram of information sequence with more symbols (7 symbols) in the last partBack to article page
