The signaling scenario illustrated by FIG. 1 and using the codeword properties defined herein, the various embodiments may combine multiple messages under the hypothesis that the value of a message portion corresponding any subsequent observed transmission is different. Accordingly a first buffer may store the first observed message frame (509) and a second buffer may sum the LLR's of subsequent observed frames (513).In the embodiments disclosed, two decoding hypotheses are required only; a first where the two buffers are combined directly (513) and a second where the difference codeword bit LLR's of the first buffer (509) are inverted before combining with those of the second buffer (519). A maximum of N transmissions is allowed by the receiver (523), after which a decoding failure is declared."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and methods for jointly decoding messages based on apriori knowledge of modified codeword transmission","description":"A method and apparatus for jointly decoding a first and second message is disclosed.
