[VHDL-FPGA-Verilog] Process_Algebra_www.softarchive.net

Description: Research towards meeting the higher demands for higher data rates was the main reason for the birth of an evolution technology towards the 4th generation mobile communication systems. This evolution to the current 3rd generation UMTS systems was given the name E-UTRA/UTRAN Long Term Evolution (LTE) by the 3GPP. This paper analyzes the requirements for this evolution and evaluates the performance of the OFDM-LTE system under different propagation impairments (AWGN and multipath fading channels involving Pedestrian and Vehicular scenarios) in terms of bit and symbol error rates (BER and SER) for different modulation formats.

[Other] SPHERE-DECODING

Description: ：在长期演进(LTE)系统中，球形译码算法拥有接近于最大似然(ML)的误码率(BER)性能。针对在 16QAM和64QAM等高阶调制情况下球形译码算法计算复杂度和所需硬件资源的急剧增加，提出了一种调整符号搜索策略的改进型球形译码算法。该算法在不同的检测层采用特定的符号搜索方案，并结合一种基于信噪比的动态调整半径方法。在无线瑞利信道环境下，对各种球形译码算法进行了仿真。仿真结果表明，提出的改进型算法基本保持传统球形译码算法较低的BER性能，同时还有效地降低了计算复杂度和硬件实现复杂度。-Motivated by the need for high throughput sphere decoding formultipleinput- multiple-output (MIMO) communication systems, we propose a parallel depth-first sphere decoding (PDSD) algorithm that provides the advantages of both parallel processing and rapid search space reduction. The PDSD algorithm is designed for efficient implementation on programmable multi-processor platforms. We investigate the trade-off between the throughput and computation overhead when the number of processing elements is 2, 4 and 8, for a 4× 4 16-QAM system across a wide range of SNR conditions. Through simulation, we show that PDSD can offer significant throughput improvement without incurring substantial computation overhead by selecting the appropriate number of processing elements according to specific SNR conditions

[Other systems] LTE-packet

Description: In Modulation schemes such as OFDM transmitter time domain signal will have higher PAPR, which leads to various distortions in the transmitter chain and degradation of system performance i.e. BER/PER. Also requires highly linear power amplifier which increases cost of the system. PAPR is ratio of peak power to average power of time domain complex baseband signal which is to be transmitted. We will discuss PAPR reduction techniques below.-In Modulation schemes such as OFDM transmitter time domain signal will have higher PAPR, which leads to various distortions in the transmitter chain and degradation of system performance i.e. BER/PER.

[Software Engineering] LTE

Description: Matlab simulation for drawing the BER plot of the LTE turbo code, using either the BCJR algorithm or the fully-parallel algorithm. Copyright (C) 2013 Robert G. Maunder The simulation can be started by running the main.m script. This can be modified to either the BCJR algorithm or the fully-parallel algorithm, as well as to the frame length N. As the simulation proceeds, it will gradually plot the BER that can be achieved using various number of decoding iterations, as selected in main.m. A greater number of decoding iterations will give a lower BER. The script main.m can also be modified to make the BER plots smoother and reach lower BERs, at the cost of making the simulation run slower.-Matlab simulation for drawing the BER plot of the LTE turbo code, using either the BCJR algorithm or the fully-parallel algorithm.
