Model laluan penghantaran yang setara ialah model saluran berorientasikan perambatan untuk meramalkan kadar ralat bit akibat gangguan intersimbol dalam sistem keluaran tunggal input tunggal. Kami melanjutkan model ini untuk membangunkan skim pengiraan baharu untuk nisbah maksimum yang menggabungkan penerimaan kepelbagaian dalam konfigurasi berbilang output input tunggal. Bahagian utama kajian adalah untuk mendapatkan formula umum yang menyatakan fungsi ketumpatan kebarangkalian bersama nisbah amplitud dan perbezaan fasa model dua laluan. Dalam derivasi ini, kami terutamanya mengambil pendekatan teori dengan bantuan simulasi Monte Carlo. Kemudian, anggaran ketepatan yang sangat tinggi bagi kadar ralat bit purata akibat gangguan intersimbol (ISI) untuk CQPSK yang dikira berdasarkan model disahkan oleh simulasi komputer. Akhir sekali, kami mencadangkan formula pengiraan yang sangat mudah untuk ramalan BER disebabkan oleh ISI yang biasa digunakan untuk pelbagai skim modulasi/penyahmodulasi, seperti CQPSK, DQPSK, 16QAM dan CBPSK dalam nisbah maksimum yang menggabungkan penerimaan kepelbagaian.

Abstract: The equivalent transmission-path model is a propagation-oriented channel model for predicting the bit error rate due to intersymbol interference in single-input single-output systems. We extend this model to develop a new calculation scheme for maximal-ratio combining diversity reception in single-input multiple-output configurations. A key part of the study is to derive a general formula expressing the joint probability density function of the amplitude ratio and phase difference of the two-path model. In this derivation, we mainly take a theoretical approach with the aid of Monte Carlo simulation. Then, very high-accuracy estimation of the average bit error rate due to intersymbol interference (ISI) for CQPSK calculated based on the model is confirmed by computer simulation. Finally, we propose a very simple calculation formula for the prediction of the BER due to ISI that is commonly applicable to various modulation/demodulation schemes, such as CQPSK, DQPSK, 16QAM, and CBPSK in maximal-ratio combining diversity reception.
