Apparatus and method for efficiently distributing energy over a packet data channel in a mobile communication system for high rate packet transmission |
摘要 |
An apparatus and method for efficiently distributing energy to a packet data channel. A turbo encoder generates a sequence of systematic symbols and a sequence of parity symbols by encoding an information bit stream. An interleaver interleaves the systematic symbol sequence and the parity symbol sequence, separately and serially concatenates the interleaved systematic symbol sequence and the interleaved parity symbol sequence. An energy distributor rearranges the concatenated symbols so that the systematic symbols are disposed in a high energy-having portion of a predetermined transmission period when transmission energy varies for the transmission period. A modulator modulates the rearranged symbols. |
