BIT INTERLEAVER FOR A MIMO SYSTEM |
摘要 |
<p>An interleaver is described for use in MIMO transmission, for use in a transmitter apparatus for generating a multi-antenna output for transmission into a MIMO channel. The transmission apparatus comprises a data source for generating a block of coded bits for transmission in a first configuration, and the interleaver is operable to permute the bits into a second configuration, and to pass the permuted data to modulating means for modulating the bits in the second configuration into an OFDM frame for transmission. The interleaving means comprises mapping means for applying a mapping function to a first value describing the position of a bit in the first configuration. The mapping means is operable to generate a second value describing the position of the bit in the second position, the relationship between the second value and the first value being based on the product of the first value and a factor co-prime with the number of bits in the block of data. A method of interleaving data, specific to MIMO transmission is also described, as is a receiver, a de-interleaver of such a receiver, and a method of receiving interleaved data.</p> |
