TRANSMITTER AND RECEIVER FOR DELAYED BIT-INTERLEAVED CODE MODULATION

摘要

The present invention provides a transmitter (200) for Delayed Bit-Interleaved Code Modulation, DBICM. The transmitter comprises a bit delay module (201) and a modulation module (202). The bit delay module (201) is configured to receive a plurality of parallel bit streams (203), delay at least one bit stream (204) of the parallel bit streams (203) to generate a plurality of realigned parallel bit streams (205), and provide the realigned parallel bit streams (205) to the modulation module (202). The modulation module (202) is configured to map the realigned parallel bit streams (205) to complex symbols (206), the complex symbols (20)6 corresponding to constellation points in a complex plane.
