| Popis: | We propose a parallel transmission to improve transmission speed using IEEE 802.11b wireless LAN standard. Parallel transmission is a method for transmitting data over two lines (frequency channel) simultaneously using one wireless station. Furthermore, we suppressed the frequency bandwidth by narrowing the frequency channel interval of each line. We applied a synchronous transmission, which controls the packet transmission timing of each line to reduce adjacent channel interference. Computer simulation results clarified the bit error rate with a synchronization gap quantity between lines for various numbers of lines and frequency channel intervals. We also examined SNR-BER performance with the number of lines and the frequency channel interval on synchronous transmission. Then, we confirmed that a parallel transmission improves transmission speed by selecting the number of lines and the frequency channel interval that are suitable for a required transmission speed and communication environment. |
