A frequency segment parser parses content of the two or more LDPC code words into a first frequency segment corresponding to a first subband of the communication channel and a second frequency segment corresponding to a second subband of the communication channel. A constellation mapper maps first content of the two or more LDPC code words to first constellation points corresponding to first OFDM tones in the first subband, and maps second content of the two or more LDPC code words to second constellation points corresponding to second OFDM tones in the second subband. A tone ordering unit reorders the first OFDM tones and the second OFDM tones such that the first content is distributed over the first subband, and the second content is distributed over the second subband."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Tone reordering in a wireless communication system","description":"One or more LDPC encoders generate two or more LDPC code words to be included entirely in an OFDM symbol.
