BIT SIGNAL STRUCTURE FOR DIFFERENTIALLY ENCODED BROADCASTS

摘要

In one embodiment, a communication device comprises a differential encoder to receive data for transmission and encode the data for transmission using a set of codes that, when processed by the differential encoder, place the differential encoder in a known state and generate uncorrelated output sequences.

1. A method comprising:
receiving, at a differential encoder, data for transmission while the differential encoder is in a first logical state; and encoding a portion of the data using a transmission code to generate an encoded signal, wherein the transmission code is selected from a set of code words, and wherein the transmission code is selected so that the differential encoder enters a second logical state that is different than the first logical state after encoding the portion of the data; and encoding a second portion of the data using a second transmission code to generate a second encoded signal, wherein the second transmission code is selected from the set of code words, and wherein the second transmission code is selected so that the differential encoder enters a third logical state that is different than the second logical state after encoding the second portion of the data.
