摘要
An integrated incremental redundancy symbol mapping diversity system for a communication device. The integrated incremental redundancy symbol mapping diversity system includes a transmitter. The transmitter packetizes a retransmission packet according to a modulation scheme in response to a retransmission request from the receiver. The transmitter includes an output packet processor and an inter-packet selective symbol mapper. The output packet processor determines a transmission iteration of a bit segment of the retransmission packet. The inter-packet selective symbol mapper applies a first symbol map pattern to the bit segment based on the transmission iteration of the bit segment and applies a second symbol map pattern to another bit segment of the retransmission packet based on the transmission iteration of the other bit segment. The first symbol map pattern is different from the second symbol map pattern.
