中文摘要：

为降低球译码算法复杂度，采用概率计算的方法，推导出多入多出（MIMO）系统的一种改进的复数域球译码算法．比较了采用经典复数域球译码算法和采用改进的复数域球译码算法的性能与复杂度．仿真结果表明，高信噪比条件下，改进算法的复杂度与发送天线数的2次方成正比．

英文摘要：

To reduce the complexity of the sphere-decoding algorithm, a modified sphere-decoding algorithm in the complex domain based on probability computation was proposed for multiple input and multiple output （MIMO）system. The performance and the complexity of the modified algorithm were compared with those of the classical sphere-decoding algorithm through simulation. With a high signal-to-noise ratio, the complexity of the modified algorithm is only a quadratic polynomial of the number of the transmit antennas.
