Precise Quadrature Signal Generation by Sampling,As mentioned in Chapter two, digital wireless receivers require quadrature demodulation schemes to keep both amplitude and phase information of the received signal. Quadrature demodulation in digital domain was originally referred as quadrature sampling, a concept introduced by Grace and Pitt [1].作者: 哪有黃油 時(shí)間: 2025-3-22 19:16
Blind Compensation of I/Q Mismatches,As pointed out in Chapter six, the gain mismatch and phase error between the I and Q channels in a quadrature receiver, adversely affect the performance of the receiver, by generating image components of the receiving signal. Its effect is very problematic in a receiver designed for multi-channel reception.作者: 哀求 時(shí)間: 2025-3-23 01:13

Currently, a majority of those discrete components can be put together to a small integrated circuit die, but hardly the image-reject filters.
