Abstract
A transmitter and a receiver for communicating data using at least two separate RF channels using channel bundling. The transmitter includes a data stream partitioner configured to partition a data stream of data to be communicated into two or more stream partitions, two or more modulators configured to each receive a stream partition and to generate modulated data from the received stream partition, and an interleaver configured to assign the modulated data generated by a modulator from a received stream partition to different RF channels for transmission.

A transmitter for communicating data using at least two RF channels, the transmitter comprising:
- circuitry configured to:

- generate plural sets of modulation cells from the plurality of stream partitions, each one of the sets of modulation cells being generated by FEC (Forward Error Correction) coding, and then bit-interleaving, and then modulation mapping a respective stream partition of the plurality of stream partitions;
- rearrange two of the sets of modulation cells to obtain two rearranged sets of modulation cells for the two RF channels, respectively, by
- applying a matrix V(even) for multiplication with an input vector of two modulation cells of an even index from the two of the sets of modulation cells, and
