摘要
Turbo码在许多方面已走向了实际应用阶段,本文在3 GPP交织器中使用了基于低码重分布的优化能量分配法,该法将不同能量分配给不同重量的码字.仿真结果表明,在不同的Eb/N0时,对BER的改善明显.
Turbo codes get to the phrase of application in many fields. In the 3 GPP interleaver, it is employed a new scheme for optimal energy allocation based on the distribution of low weight codewords which allocates energies to the different codewords that have different weights. The simulations show that the improvements for the BER are very apparent for the different Eb/N0.
