The main objective of the proposed research programme is to develop, extend and demonstrate a methodology for using field-programmable gate arrays (FPGAs) to greatly accelerate the simulation of wireless communication systems. The designers of multiple-antenna wireless communication systems face a rapidly escalating challenge where the designs of proposed transmitters and receivers must be verified and optimized over a wide range of posssible design configurations and wireless channel conditions. The performance of each candidate design must be verified using long-running simulations with pseudorandomly generated data communicated over realistic but complex models of the wireless channel. To ensure statistically meaningful bit and and symbol error rate (BER and SER) measurements, the simulated communication systems must process an extremely large number of transmitted data bits. This situation is made worse by the use of powerful error correcting codes, such as Turbo codes, which further reduce the effective BER and SER for the same channel conditions and hence lengthen the required simulations. Consequently conventional software-based simulations can easily take many days and even weeks of time on even the fastest computer workstations.

拟议研究计划的主要目标是开发、扩展和演示一种使用现场可编程门阵列 (FPGA) 来大大加速无线通信系统仿真的方法。 多天线无线通信系统的设计人员面临着快速升级的挑战，其中所提出的发射器和接收器的设计必须在各种可能的设计配置和无线信道条件下进行验证和优化。 每个候选设计的性能必须使用长时间运行的仿真进行验证，并通过真实但复杂的无线信道模型传输伪随机生成的数据。 为了确保具有统计意义的比特和误码率（BER 和 SER）测量，模拟通信系统必须处理大量的传输数据比特。 使用强大的纠错码（例如 Turbo 码）会使这种情况变得更糟，这进一步降低了相同信道条件下的有效 BER 和 SER，从而延长了所需的模拟时间。 因此，即使在最快的计算机工作站上，传统的基于软件的模拟也很容易花费数天甚至数周的时间。
