Signal Processing for Communication Systems
5G standardization: Collaborative effort between 3GPP and ITU, ensuring global interoperability and compatibility for next-gen mobile networks. ITU ITU stands for the International Telecommunication Union. It is a specialized agency of the United Nations responsible for the development and coordination of international telecommunications standards and regulations. The ITU plays a crucial role in ensuring global … Read more
Key focus: Bandwidth Part (BWP): Allocates segments of spectrum for flexible resource allocation in 5G NR networks, enhancing efficiency and adaptability. Know the difference between bandwidth part and transmission bandwidth Introduction The 3rd Generation Partnership Project (3GPP), in its Release 15, specified the new radio-access technology called 5G New Radio (5G NR). The 5G NR … Read more
Key focus: Volterra series is an useful tool for modeling nonlinear time invariant systems in general, and they are commonly used to model RF power amplifiers with memory effects Introduction Power amplifier are nonlinear devices responsible for compensating for the signal power loss between a transmitter and receiver. The input power levels to the power … Read more
Key focus: 5G NR resource block : a block of 14 OFDM symbols (1 slot across time domain) with the corresponding 12 subcarriers for those symbols 5G NR protocol stack In the 5G New Radio (NR), the protocol architecture can be separated into two categories: user plane protocol stack and control plane protocol stack. The … Read more
