Bit Error Rate (BER) is one of the main parameters in assessing the performance of digital communication systems. In this research, BER analysis was carried out on the Paired Carrier Multiple Access (PCMA) Very Small Aperture Terminal Single Channel Per Carrier (VSAT SCPC) scheme which was applied to the Turbo Product Code (TPC). PCMA is a transmission technique that allows the use of limited power to increase frequency spectrum efficiency, while TPC is used as an error correction technique to increase the reliability of data transmission. Conventional VSAT SCPC requires two carrier frequencies to communicate while PCMA SCPC only requires one carrier frequency so it is more efficient in bandwidth usage. There are two possibilities for SCPC PCMA, namely Power Limited or Bandwidth Limited. This research discusses how SCPC Power Limited is converted into bandwidth limited and its effect on transponder efficiency and the resulting Bit Error Rate (BER). The research results show that changing power limited to bandwidth limited SCPC PCMA Turbo Product Code increases bandwidth efficiency but reduces the quality of the bit error rate.
