Strategies for Handling High Peak Power in LTE Transmitters

摘要

Orthogonal frequency division multiple access (OFDMA) offers many advantages to LTE, notably the ability to deliver high data rates and perform well even in low quality channels. However, the technology does present some difficulties. In OFDMArnsystems, the peak-to-average power ratio (PAPR) of composite signals can have peaks that exceed 12 dB above the average signal power. This complicates signal transmission by an e-Node B (eNB or base station) operating at high power.
