摘　　要：介绍一种用砷化镓场效应管实现宽带信号的倍频技术,该技术具有有源倍频的有增益、单向性及隔离度好、稳定性好等特点,并对其进行了仿真实验,结果表明:使用砷化镓场效应管实现的宽带有源倍频是低次倍频中一种有效的技术手段。A modified TURBO algorithm is proposed with efficient operation. This algorithm remarkably reduces the amount of hardware of the TURBO decoder, where the scale of decoder memories can be reduced to the half memories required by conventional algorithms. Based on the modified TURBO algorithm, a new Add-Compare-Select （ACS） unit is designed. The simulation results show that the area and power consumption of proposed ACS unit are 32.7% and 26.8% of conventional ACS units, respectively.
