Description: A 2by3 MIMO model using Simulink. The decoder uses zero forcing algorithm. Set in the workspace the modulation order (QAM modulation), Doppler shift, SNR in dB, bit rate, sample per frame, max number of bits and max number of errors before running the simulation. Works also with BERTool but change the BER variable to ErrorVec. Included in the file a BER session with multiple runs and a figure for several runs.

Description: BER verses SNR in ofdm with amplifier:
The BER performances of OFDM systems over the AWGN channel are given
by the BER where N=512. We see that SNR required for BER=10-3
No channel coding scheme is adopted. Therefore, BER
is a bit higher. The results with 16 QAM show that the required Signal to Noise
Ratio (SNR) for BER=10-2 is almost the same. This is because the noise is the
dominant.

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
