Intercarrier Interference Compression in OFDM Communication Systems by Using Correlative Coding
DOI:10.1109/4234.709435.png)
摘要
En 中文
This study considers the use of frequency-domain correlative coding with correlation polynomial F (D) = 1 - D in OFDM mobile communication systems to compress the intercarrier interference caused by channel frequency errors. A theoretical expression of carrier-to-interference power ratio (CIR) has been derived. It shows that such a simple coding method enhances system CIR by 3.5 dB, without reducing bandwidth efficiency.
