Abstract
A power line carrier transmission apparatus according to an aspect of the present invention is a power line carrier transmission apparatus that transmits a transmission symbol via a transmission path. The transmission apparatus includes a frequency/time interleave unit that interleaves the transmission symbol, an OFDM modulation unit that OFDM-modulates the interleaved transmission symbol, a time-domain repeated transmission unit that repeatedly transmits the transmission symbol, which is modulated by the OFDM modulation unit, M times (M is an integer larger than 1) in a time domain.
Claims10
A power line carrier transmission apparatus for transmitting a transmission symbol via a power line comprising:
- an interleave unit for interleaving the transmission symbol;
- a modulation unit for OFDM-modulating the transmission symbol interleaved by the interleave unit;
- and
- a transmission unit for repeatedly transmitting the transmission symbol modulated by the modulation unit M times (where M is an integer larger than 1).
