概要
- 論文の詳細を見る
In this letter, a concise formula for the SNR degradation of OFDM caused by carrier frequency offset is derived by approximations over a shadowed two-path channel which explicitly shows the sensitivity of SNR degradation to various parameters including the frequency offset It is shown that, for small frequency offset, the SNR degradation is proportional to the square of the frequency offset and the square of the number of subcarriers It is also shown that, if E_5/N_0o is reasonably large, the SNR degradation becomes insensitive to E_5/N_0, which is contrary to the case of the AWGN channel
