Hierarchical modulation and demodulation apparatus and method
摘要
<p>An apparatus and method for hierarchical modulation and demodulation in a wireless communication network are provided. A hierarchical modulation apparatus may map information bits to a plurality of levels based on a predetermined level map, may generate an error verification code for each of the levels based on the information bits mapped to the levels, may generate coded information bits for each of the levels, and may map bits in a predetermined position among the coded information bits, to Pulse-Position Modulation (PPM) symbols in a sequence of the levels.</p>
