Dalam surat ini, anggaran bentuk tertutup untuk kadar jumlah purata pembentukan pancaran rawak diperolehi. Ia menyediakan anggaran yang hampir tepat untuk bilangan rasuk, pengguna dan SNR yang diterima secara arbitrari. Anggaran juga digunakan pada skema pembentuk rasuk rawak multimod deria purata yang mengoptimumkan bilangan rasuk rawak tanpa sebarang jenis maklumat saluran serta-merta. Skim yang dicadangkan menunjukkan prestasi kadar jumlah yang lebih baik daripada pembentukan pancaran rawak serta skema pembentukan pancaran rawak mod dwi sedia ada berdasarkan maklumat saluran segera, manakala bilangan bit maklum balas untuk indeks pancaran dikurangkan berbanding dengan pembentukan pancaran rawak.

Abstract: In this letter, a closed form approximation for the average sum rate of random beamforming is derived. It provides a near-exact approximation for arbitrary numbers of beams, users, and received SNR. The approximation is also applied to an average-sense multimode random beamforming scheme which optimizes the number of random beams without any type of instantaneous channel information. The proposed scheme shows better sum rate performance than random beamforming as well as an existing dual mode random beamforming scheme based on instantaneous channel information, while the number of feedback bits for beam index is reduced compared to random beamforming.

It provides a near-exact approximation for arbitrary numbers of beams, users, and received SNR. The approximation is also applied to an average-sense multimode random beamforming scheme which optimizes the number of random beams without any type of instantaneous channel information. The proposed scheme shows better sum rate performance than random beamforming as well as an existing dual mode random beamforming scheme based on instantaneous channel information, while the number of feedback bits for beam index is reduced compared to random beamforming.
