  • Abstract In this paper, we implement LDPC CODE in ZIGBEE (CC2430 chip) platform
    to improve the error rate. In the short-range wireless transmission technology,
    ZIGBEE is a popular new technology. Its advantages are low cost, low power, small
    size, easy to structure, etc.
    Control signal, sensing data is mainly transmitted data in ZIGBEE. This type of
    information required less bandwidth. It means that data transfer is relatively small, but
    its importance is very high. Such information, if an error occurs, it will have a serious
    impact. Therefore, a fixed bandwidth, we can use this space to improve its error rate.
    Add error correction code to each transmission data. Although this will increase the
    amount of data transferred, but its advantage is that accuracy will improve.
    In this paper, we added the LDPC CODE to improve the error rate. LDPC
    CODE is an error correction code. It is more popular in recent years, because its
    performance is very close to the Shannon Limit. The hardware decoder is simple and
    low cost. It is relatively good on the performance and complexity. In the
    implementation system, we produce MP3 data by recording, and then send data
    through ZIGBEE. At the receiving PC side, when get all data then will play MP3
    music. Comparison of the effect of this improvement.
