| Summary: | Wireless radio communication is expected to reach long distances with good
quality. To achieve long-range radio communication, relay stations can be added
between the source and destination points as needed. The wireless radio results in
communication quality disturbances due to noise and interference. Therefore,
detection and correction of errors in the received information are required. In this
thesis, a multihop communication system was created using four stationary LoRa
nodes. The Multihop LoRa system using a (32,16) reguler binary LDPC encoder
for error correction and detection. Node-02 and node-03 as repeaters between
node-01 and node-04. The LDPC decoder used is the Peeling technique. Each node
is implemented using beaglebone black Industrial and LoRa ebyte. The software
used includes debian console and python programming. Testing the multihop LoRa
communication with LDPC peeling decoding will obtain information parameters
such as multihop communication delay , error detection capability, and error
correction capability, and RSSI LoRa. |
