摘要: In traditional receiver architectures, frame synchronization is performed using pilot symbols and a correlation rule. this paper we show that outputs from the constraint node side of bipartite decoding graph can be used to achieve in pilotless low-density parity-check (LDPC) coded transmission, thereby avoiding bandwidth cost inherent use symbols. The complexity synchronizer kept relatively low due its XOR-based approach.
