在无线通信系统全面进入3G并开始迈向 4G的过程中,使用数字预失真技术(Digital Pre-distortion,以下简称DPD)对发射机的功放进行线性化是一门关键技术。功率放大器是通信系统中影响系统性能和覆盖范围的关键部件,非线性是功放的固有特性。非线性会引起频谱增长(spectral re-...
在现代通信系统中,电话语音的频带被限制在300 Hz~4 kHz的范围内,带来了语音可懂度和自然度的降低。为了在不增加额外成本的前提下提高语音的可懂度和自然度,进行了电话语音频带扩展的研究。提出了一种改进的基于码本映射的语音带宽扩展算法:在码本映射的过程中,使用加权系数来得到映射码本。客观测试结果表...
ACPR (adjacent channel power ratio), AltCPR (alternatechannel power ratio), and noise are important performancemetrics for digital communic...
