Bit Error Rate (BER) Performance of MIMO Systems in M QAM with Nonlinear Effect

open access: yesInternational Journal of Engineering and Advanced Technology, 2019
Out object in this paper it to study, the effect of nonlinearity on the bit error rate (BER) of MIMO systems in M-QAM modulation techniques. We consider Saleh’s model (power amplifier model) for the nonlinearity, and apply the nonlinear model on MIMO system with receiver diversity and transmitter diversity.

BER Evaluation Based SCFlip Algorithm for Polar Codes Decoding

open access: yesIEEE Access, 2020
Successive cancellation (SC) decoding of polar codes may bring about error propagation that needs to be mitigated. In this paper, we present a new SC Flipping (SCFlip) decoder, named bit error rate (BER) evaluation based SCFlip (BER-SCFlip), which can ...

Optimalisasi Bit Error Rate (BER) Jaringan Optik Hybrid Pada Sistem DWDM Berbasis Soliton

open access: yesJournal of Telecommunication, Electronics, and Control Engineering (JTECE), 2021
Abstrak Bit Error Rate (BER) merupakan perbandingan antara kesalahan (error) dengan bit yang dikirimkan keseluruhan. Bit Error Rate berfungsi untuk menguji seberapa banyak kesalahan pembacaan di sisi penerima setiap detiknya. Berdasarkan pengertian dari BER peneliti akan melakukan penelitian performansi Bit Error Rate terhadap pengaruh perubahan ...
