ABSTRACT:
A method and apparatus increase the time and frequency diversity of a multi-stream signal in a DAB system. A plurality of audio streams are divided into four (4) digital sub-streams, C00, C01, C10, and C11. Each sub-stream C00, C01, C10, and C11is assigned a unique frequency band, and time slot. A first core sub-stream C10is mapped to one frequency partition and a second core sub-stream C00is mapped to another frequency partition and delayed relative to the first core sub-stream. Similarly, two enhancement sub-streams C11and C01are mapped to different frequency partitions and are time delayed relative to each other and the core sub-streams. The two core sub-streams C00and C10can have a maximum separation across both the time and frequency axes.
