【期刊論文】基于DF全雙工MIMO中繼網絡系統的高性能波束成形和低復雜度檢測算法
束鋒, Feng Shu, Ye Zhou, Riqing Chen, Jin Wang, Jun Li, Branka Vucetic
China Communications (accepted),-0001,():

In this paper, we consider a full-duplex multiple-input multiple-output (MIMO) relaying network with the decode-and-forward (DF) protocol. Due to the full-duplex transmissions, the self-interference from the relay transmitter to the relay receiver degrades the system performance. We thus propose an iterative beamforming structure (IBS) to mitigate the self-interference. In this method, the receive beamforming at the relay is optimized to maximize the received signal-to-interference-plus-noise-ratio (Max-SINR), while the transmit beamforming at the relay is optimized to maximize the signal-to-leakage-plusnoise-ratio (Max-SLNR). To further improve the performance, the receive and transmit beamforming matrices are optimized between Max-SINR and Max-SLNR in an iterative manner. Furthermore, in the presence of the residual self-interference, a low-complexity whitening-filter (WF) maximum likelihood (ML) detector is proposed. In this detector, a WF is designed to transform a colored interference-plus-noise to a white noise, while the singular value decomposition is used to convert coupled spatial subchannels to parallel independent ones. From simulations, we find that the proposed IBS performs much better than the existing schemes. Also, the proposed low-complexity detector significantly reduces the complexity of the conventional ML (CML) detector from exponential time (an exponential function of the number of the source transmit antennas) to polynomial one while achieving a slightly better BER performance than the CML due to interference whitening.

【期刊論文】非理想信道狀態信息下多用戶對雙向中繼系統自適應穩健波束成形

In wideband multi-pair two-way relay networks, the performance of beamforming at a relay station (RS) is intimately related to the accuracy of the channel state information (CSI) available. The accuracy of CSI is determined by Doppler spread, delay between beamforming and channel estimation, and density of pilot symbols, including transmit power of pilot symbols. The coefficient of the Gaussian-Markov CSI error model is modeled as a function of CSI delay, Doppler spread, and signal-to-noise ratio, and can be estimated in real time. In accordance with the real-time estimated coefficients of the error model, an adaptive robust maximum signal-to-interferenceand-noise ratio (Max-SINR) plus maximum signal-to-leakage-and-noise ratio (Max-SLNR) beamformer at an RS is proposed to track the variation of the CSI error. From simulation results and analysis, it is shown that: compared to existing non-adaptive beamformers, the proposed adaptive beamformer is more robust and performs much better in the sense of bit error rate (BER); with increase in the density of transmit pilot symbols, its BER and sum-rate performances tend to those of the beamformer of Max-SINR plus Max-SLNR with ideal CSI.

In this paper, spatial channel pairing (SCP) is introduced to coherent combining at the relay in relay networks. Given SCP, the closed-form solution to the optimal coherent combining is derived. Given coherent combining, the approximate SCP solution is presented. Finally, an alternating iterative structure is developed. From simulation results and analysis, we find: given symbol error rate and data rate, the proposed alternating iterative structure achieves several signal-to-noise ratio gains over existing schemes in maximum ratio combining (MRC) plus matched filter, MRC plus antenna selection, and distributed space-time block coding due to the use of SCP and iterative structure.

本文根據DFT的一個性質為OFDM通信系統構造了一種通用信道估計模型。該模型利用系統子信道中的一部分專門進行信道估計,適用于慢消失信道。該模型同最小平方差(LS)和最小均方差(LMMSE)相結合分別形成兩種信道估計方法,并從理論角度分別分析它們的計算復雜性和均方差性能。對多徑信道仿真表明,基于LS的方法誤符號率性能比基于LMMSE的方法差2-3dB,但是計算復雜度較低??傊?,此信道估計模型的計算復雜度和性能隨著用于信道估計的子信道數目增加而增加,當所用子信道數目是周期頭長度的兩倍時,達到計算量和估計性能的最佳平衡。

該文提出一種基于頻域的幅度兩電平的DAPSK+OFDM,并討論該調制方式在頻域的差分調制和解調,然后給出它在白高斯信道的誤比特性能公式,最后在典型的調幅(AM)波段信道對它和基于時域的DAPSK+OFDM的誤比特性能進行了仿真。結果表明:在短波信道,頻域的DAPSK+OFDM比時域的DAPSK+OFDM性能好;在中波信道,時域的DAPSK+OFDM比頻域的DAPSK+OFDM性能好。因此,數字調幅廣播系統在短波信道可采用頻域DAPSK+OFDM,在中長波信道可采用時域DAPSK+OFDM。

數字調幅廣播(DAMB)需要高速的數據傳輸率,為此本文提出一種具有高帶寬效率的編碼調制方案。采用16差分幅度相位(16DAPSK)加正交頻分復用(OFDM)調制,采用多級碼(MLC)作為糾錯編碼,其分量碼為標準卷積碼及其刪除型卷積碼,系統具有高的帶寬利用率,抗多徑傳輸,接收端可以并行解碼,以減小通常逐層解碼所帶來的大的時延和誤差傳播,并且由于差分調制的引入,接收端可以采用非相關檢測,且毋須均衡器,簡化了接收機的設計,本文還比較了短波信道中,采用時域差分和頻域差分的效果,并得出了相應的結論。

作為時變的多徑信道,中短波信道的時變性導致基于OFDM數字調幅廣播系統各個子信道間產生干擾,簡稱ICI。該文首先分析OFDM系統在一般時變多徑信道的模型,在此基礎上推導了中短波信道時變特性在OFDM系統中所產生的ICI公式,最后利用該公式通過計算機數值計算確定在ICI可忽略不計的情況下,OFDM系統的總的子載波數目N的最大值,而該值的確定對于基于OFDM的數字調幅廣播系統是非常重要的

提出了一種具有高頻帶利用率和高重建質量的聯合編碼調制算法。采用Turbo碼網格編碼調制TTCM作為編碼調制(CM)方案,按“最小化端到端失真”準則最優化設計信源解碼器,直接利用TTCM解碼輸出的軟判決值進行信源譯碼。仿真表明,相對于硬判決分離譯碼,本文算法將重建信號的信噪比提高了約2dB。

Digital AM broadcasting (DAMB) channels are investigated in detail. First, the normalised ICI power of time-variant DAMB channels is calculated to determine the range of total subcarriers of an OFDM-based DAMB system. The number of subcarriers provides a base for the subsequent channel estimation. Then, two time-frequency channel estimators with real coefficients are constructed and analysed for a DAMB system based on OFDM. Finally, their BER performance is simulated in DAMB channels. In conclusion, the 1-D estimator provides a better trade-off between BER performance and computational complexity than a 2-D estimator. The low complexity of a 1-D estimator makes it suitable for use in wireless communication systems such as WLAN, DVB and so on.

由于無線信道的時變性、頻率選擇性、加性噪聲以及發送和接收端晶體振蕩器頻率非一致性的影響,實際的OFDM系統中總存在時間和頻率同步誤差。定義了歸一化干擾功率(NIP)來研究這兩種誤差對系統性能的影響。在此基礎上,我們首先推導出:(1)由時間誤差產生的NIP公式和它的兩個上界;(2)由頻率同步誤差產生的NIP公式和它的兩個上界,這兩個界比Moose上界更逼近實際NIP值。然后,通過在典型短波和中波信道的仿真進一步驗證了這些界的有效性和正確性。這些界有助于通信工程師在實際應用中在給定NIP值的條件下選擇滿足系統要求的時間和頻率同步算法。同時,還提出一種新的方法以減少OFDM系統對時間同步算法的精度要求,該算法能實現時間同步精度和頻譜利用率的有效平衡。
