Makalah ini mencadangkan proses pembatalan puncak (PC) selari untuk algoritma cekap kerumitan pengiraan yang dipanggil PC dengan kekangan saluran-null (PCCNC) dalam kaedah pengurangan nisbah kuasa puncak kepada purata (PAPR) adaptif menggunakan ruang nol dalam saluran berbilang input berbilang keluaran (MIMO) untuk isyarat pemultipleksan pembahagian frekuensi ortogon (OFDM) MIMO. Dengan menambahkan berbilang isyarat PC secara serentak pada vektor isyarat penghantaran domain masa, bilangan lelaran yang diperlukan bagi algoritma lelaran dikurangkan dengan berkesan bersama-sama dengan PAPR. Kami melaksanakan kekangan di mana isyarat PC dihantar hanya ke ruang nol dalam saluran MIMO oleh beamforming (BF). Dengan berbuat demikian, aliran data tidak mengalami gangguan daripada isyarat PC di bahagian penerima. Memandangkan operasi transformasi Fourier pantas (FFT) dan FFT songsang (IFFT) pada setiap lelaran tidak diperlukan tidak seperti algoritma sebelumnya dan terima kasih kepada pendekatan pemprosesan selari yang baru diperkenalkan, algoritma PCCNC yang dipertingkatkan mengurangkan jumlah kerumitan pengiraan yang diperlukan dan bilangan lelaran berbanding kepada algoritma sebelumnya sambil mencapai prestasi throughput-vs.-PAPR yang sama.

Abstract: This paper proposes a parallel peak cancellation (PC) process for the computational complexity-efficient algorithm called PC with a channel-null constraint (PCCNC) in the adaptive peak-to-average power ratio (PAPR) reduction method using the null space in a multiple-input multiple-output (MIMO) channel for MIMO-orthogonal frequency division multiplexing (OFDM) signals. By simultaneously adding multiple PC signals to the time-domain transmission signal vector, the required number of iterations of the iterative algorithm is effectively reduced along with the PAPR. We implement a constraint in which the PC signal is transmitted only to the null space in the MIMO channel by beamforming (BF). By doing so the data streams do not experience interference from the PC signal on the receiver side. Since the fast Fourier transform (FFT) and inverse FFT (IFFT) operations at each iteration are not required unlike the previous algorithm and thanks to the newly introduced parallel processing approach, the enhanced PCCNC algorithm reduces the required total computational complexity and number of iterations compared to the previous algorithms while achieving the same throughput-vs.-PAPR performance.
