Paper ini menampilkan sebuah penerima adaptif selektif (selective adaptive (SA) receiver), untuk sistem Multicarrier Direct Sequence Code Division Multiple Access (MC DS-CDMA). Penerima ini memiliki performa yang tinggi dan sekaligus mengurangi multiple access interference (MAI) pada sistem MC DS- CDMA dengan tingkat kompleksitas komputasi yang rendah. Kinerja SA receiver diukur pada aspek bit error rate (BER). Suatu persamaan batas atas untuk BER pada SA receiver di bawah kondisi Rayleigh fading channel diturunkan dan divalidasi dengan simulasi komputer. Selanjutnya, tingkat kompleksitas implementasi dari SA receiver dibandingkan dengan tingkat kompleksitas implementasi Adaptive Parallel
Interference Cancellation (APIC) receiver.
In this paper, selective adaptive (SA) receiver for Multicarrier Direct Sequence Code Division Multiple Access (MC DS-CDMA) system is presented. This receiver has high performance and at the same time reduces the multiple access interference (MAI) of the MC DS-CDMA) system with low computational complexity. The performance of SA receiver is measured in terms of the bit error rate (BER). An upper
bound expression of the BER for the SA receiver under Rayleigh fading channel condition is derived and validated by computer simulations. Moreover, the implementation complexities of the SA receiver is compared with the Adaptive Parallel Interference Cancellation (APIC) receiver.
