The Research of OFDM Modulation and Demodulation Technology Based on Wavelet Packet
With the development and improvement of wireless communication technology, the technology of orthogonal frequency division multiplexing (OFDM) has caused wide attention. In the system of OFDM, with the deserializing, highspeed data string increases the lasting time of data symbol on each subcarrier, reduces inter-symbol interference effectively which comes from time dispersion of radio channel, and provides the possibility for future high-speed wireless data business. However, the interference existing in actual power lines signal channel, especially of multipath effect, is further intensify the ICI and meanwhile causes the LSI. In this paper, the OFDM system based on wavelet packet not only decreases the complexity, but also improves antijamming ability.
