The increasingly demanding performance requirements of communications systems, as well as problems posed by the continued scaling of silicon technology, present numerous challenges for the design of frequency synthesizers in modern transceivers.

通信系统的性能要求越来越苛刻，以及由硅技术不断提升，为在现代收发器频率合成器的设计带来许多挑战造成的问题。

Firstly, a simple closed-form MIMO channel capacity formula is derived by using the eigenvalue distribution of Wishart matrix.

首先，利用Wishart矩阵的特征值分布，导出了一个简单闭合的MIMO信道容量公式；然后基于此公式，得到了MIMO信道容量在高信噪比时的渐近界，解析地反映了随着信噪比的逐渐增加，MIMO信道容量与信噪比和收发天线数目的最小值呈渐近的线性关系；最后，计算机仿真验证了所提出的MIMO信道容量公式及其渐近界的正确性。

During the design of VXI-bus Serial Controller Module, the functions of VXI-bus including time-sequence for VXI interface, resource management, interrupt process, bus arbitration, are accomplished. To advance the performance and stability, the FPGA technic is used to implement the kerneled code including serial bus time-sequence switching to VXI interface time-sequence, the UART, the Parameterized Baud Generator and"Pipeling frame". The handle type of Data Transfer Bus for VXI-bus is researched thoroughly, and the format of serial data transfer is designed.

在VXI总线串行控制器设计中，实现了VXI总线控制器的基本功能，包括VXI总线接口时序、总线仲裁、超时处理等；同时利用先进的FPGA技术实现了串行总线时序向VXI总线时序的转换、通用异步收发器、参数化波特率发生器、流水线结构等功能模块；在设计中还深入研究了VXI总线数据传输的各种操作类型，制定了串行数据传输的编码格式。
