Since wireless communication systems supply a large amount of packet-sized (non-binary) data, a channel coding technique that can efficiently correct errors caused by channels is required. This paper focuses on systematic Low-Density Parity-Check (LDPC) code for non-binary codes with symbol size of at least 32 bits/symbol and investigates the transmission of non-binary data under different channel conditions through Message Passing Telemetry Transport (MQTT). Hard decision Message Passing-Vector Symbol Decoding (hMP-VSD) is used as a decoder of systematic LDPC. The encoder and decoder are implemented on the Raspberry Pi (R-pi) boards, and the wireless transmission is done by using the Wi-Fi module.
