INTERLEAVING CIRCUIT FOR A MULTIBAND OFDM TRANSCEIVER |
摘要 |
<p>Interleaving circuit for a multiband OFDM (orthogonal frequency division multiplexing) transceiver of a ultra wide band wireless personal access network transmitting OFDM modulated symbols, wherein each OFDM symbol consists of a predetermined number (NCBPS) of encoded bits, said interleaving circuit comprising a symbol interleaving unit which receives an input bitstream of encoded bits and permutes adjacent bits of said input bitstream across different OFDM symbols; an intra-symbol tone interleaving unit which receives the bits permuted by said symbol interleaving unit and permutes adjacent bits of each OFDM symbol across uncorrelated data sub-carriers; and an intra- symbol cyclic shift unit which shifts cyclically NCBPS bits of each OFDM symbol in response to a shift value (K) which is changed between adjacent OFDM symbols.</p> |
