Kertas kerja ini menerangkan pembentuk pancaran digital bukan buta untuk sistem SDMA (akses berbilang bahagian ruang) yang digunakan apabila saluran dihadkan kuasa. Antena tatasusunan dengan banyak elemen biasanya diperlukan untuk mendapatkan keuntungan antena yang tinggi untuk penerimaan isyarat tahap rendah yang dikehendaki dan tahap kebebasan untuk diskriminasi spatial ramai pengguna menggunakan frekuensi yang sama. Pembentuk rasuk yang dicadangkan direka bentuk untuk antena tatasusunan sedemikian dengan menggunakan gabungan bekas berbilang rasuk dan teknik gabungan nisbah-maksimum (MRC). Teknik BSMM dilanjutkan kepada penggabung bukan buta yang menggunakan urutan latihan yang terkandung dalam isyarat yang dikehendaki. Analisis asas dan simulasi berangka prestasinya, di bawah keadaan terhad kuasa dan dengan terminal pengguna tetap, menunjukkan bahawa kelajuan dan keteguhan pemerolehan isyarat yang diingini dan penindasan isyarat yang tidak diingini mungkin mengatasi prestasi rekursif-kuadrat-kuadrat-kuadrat (RLS) dengan kurang pengiraan, apabila ia digunakan pada antena tatasusunan dengan banyak elemen.

Abstract: This paper describes a nonblind digital beamformer for SDMA (space division multiple access) systems used when channels are power-limited. An array antenna with many elements is usually required to obtain high antenna gain for the reception of a low-level desired signal and the degree of freedom for the spatial discrimination of many users using the same frequency. The proposed beamformer is designed for such array antennas by employing the combination of a multibeam former and a maximal-ratio-combining (MRC) technique. The MRC technique is extended to a nonblind combiner that uses a training sequence contained in the desired signal. Basic analysis and numerical simulations of its performance, under the power-limited condition and with fixed user terminals, show that the speed and robustness of desired-signal acquisition and undesired-signal suppression may outperform recursive-least-squares (RLS) beamformer with less computation, when it is applied to an array antenna with many elements.
