Method to Increase Data Rate/Robustness by Using Ternary Precoded Signals for Transmission

摘要

A method (400) for the modulation of a signal with first binary data (111) is described. The first binary data (111) include a sequence of first binary numbers a(k), where each first binary number a(k) can assume either a first binary numerical value or a second binary numerical value. The method (400) includes the generation (401) of ternary data (312), in which the ternary data (312) include a sequence of ternary numbers α(k) and each ternary number α(k) can assume a first, second, or third ternary numerical value. The method (400) also includes the modulation (402) of a phase of the signal with the ternary data (312), in which the phase of the signal can assume M different phase states (230), where M>2, and the first, second, and third ternary numerical values correspond to first, second, and third state transitions (220) between the M phase states (230). In the first state transition (222), a phase state (230) is maintained. On the other hand, the second state transition (221) and third state transition (223) produce a change in the phase state (230). The ternary data (312) are generated in such a way that all first binary numbers a(k) with the first binary numerical value are allocated to ternary numbers α(k) with the first ternary numerical value. In addition, the ternary data (312) are generated in such a way that all first binary numbers a(k) with the second binary numerical value are allocated to ternary numbers α(k) with the second or third ternary numerical value so that in the sequence of ternary numbers α(k), the second ternary numerical value does not directly follow the third ternary numerical value and vice versa.
