time-cost tradeoff function 时间成本平衡函数
Methods: Filtering different noises in ECG signals by adopting threshold function of soft-and-hard threshold tradeoff and self-adapting threshold policies.
方法：采用软、硬阈值折衷的阈值函数及自适应的阈值策略对心电信号中的不同噪声进行滤除。
Through modifying the object function of the new algorithm, a proper tradeoff can be realized between LTF and ALTF for more satisfying performance parameters of LDPC codes.
该算法不仅可以进一步提高优化性能，还可以通过修改目标函数在下三角和准下三角之间合理均衡以便确定LDPC编码优化的最佳性能参数。
