Instantaneous channel state information
http://web.mit.edu/6.441/spring05/reading/IT-V45-N6.pdf There are basically two levels of CSI, namely instantaneous CSI and statistical CSI. Instantaneous CSI (or short-term CSI) means that the current channel conditions are known, which can be viewed as knowing the impulse response of a digital filter. This gives an opportunity to adapt the transmitted signal to the impulse … Se mer In wireless communications, channel state information (CSI) is the known channel properties of a communication link. This information describes how a signal propagates from the transmitter to the receiver and … Se mer Since the channel conditions vary, instantaneous CSI needs to be estimated on a short-term basis. A popular approach is so-called training sequence (or pilot sequence), where a … Se mer • Channel sounding Se mer In a narrowband flat-fading channel with multiple transmit and receive antennas (MIMO), the system is modeled as $${\displaystyle \mathbf {y} =\mathbf {H} \mathbf {x} +\mathbf {n} }$$ where $${\displaystyle \scriptstyle \mathbf {y} }$$ Se mer In a data-aided approach, the channel estimation is based on some known data, which is known both at the transmitter and at the receiver, such as training sequences or pilot data. In a blind … Se mer • Atheros CSI Tool • Linux 802.11n CSI Tool Se mer

Nettet20. des. 2024 · In this paper, we propose a practical structured constellation for non-coherent communication with a single transmit antenna over Rayleigh flat and block fading channel without instantaneous channel state information. The constellation symbols belong to the Grassmannian of lines and are defined up to a complex scaling. The … Nettetchannel state and the CSI signals are jointly independent and identically distributed (i.i.d.), the channel reduces to a case studied by Shannon. In this case, we show that when …
