Techniques for using multiple modulation schemes for a single packet are described. Each data packet is processed and transmitted in up to T blocks where T > 1. Multiple modulation schemes are used for the T blocks to achieve good performance. A transmitter encodes a data packet to generate code bits. The transmitter then forms a block of code bits with the code bits generated for the packet, determines the modulation scheme to use for the block (e.g. based on a mode/rate selected for the packet) maps the code bits for the , block based on the modulation scheme to obtain data symbols and processes and , transmits the block of data symbols to a receiver. The transmitter generates and …
