Power line carrier transmission apparatus and communication system

摘要

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.

主权项

1. A communication system comprising:
a power line carrier transmission apparatus for transmitting a transmission symbol via a power line, wherein the power line carrier transmission apparatus comprises:
an interleave unit for interleaving the transmission symbol;a modulation unit for OFDM (Orthogonal Frequency Division Multiplexing)-modulating the transmission symbol interleaved by the interleave unit; anda transmission unit for repeatedly transmitting the transmission symbol modulated by the modulation unit M times (where M is an integer larger than 1); and a reception apparatus for receiving M symbols (where M denotes the number of the symbols) created by the transmission symbol being transmitted M times by the power line carrier transmission apparatus via a power line, wherein the reception apparatus includes:
a composition unit for performing composition using the symbols in a time domain; anda deinterleave unit for deinterleaving a symbol composed by the composition unit.
