在该贡献中，在给定的固定数据吞吐量的约束下，激活的MIMO层的数量和每个符号的比特数沿着与发射功率的适当分配和BICM纠错码的速率一起被联合优化。性能调查进行了计算机模拟和确认的EXIT图表。我们的研究结果表明，不一定所有的MIMO层都必须被激活，以实现最佳的BER。
In this contribution the number of activated MIMO layers and the number of bits per symbol along with the appropriate allocation of the transmit power and the rate of the BICM error correcting codes are jointly optimized under the constraint of a given fixed data throughput. The performance investigations are carried out by computer simulations and confirmed by the EXIT charts. Our results show that not necessarily all MIMO layers have to be activated in order to achieve the best BERs.
