Abstract
Processing the exponentially growing amount of data produced daily requires efficient communication between different processing units in a computer. Traditionally, wired interconnects have been used to maintain these data links due to their energy efficiency and ability to support high data rates. However, as computing demands continue to increase in size and speed, these wired interconnects can become longer and less effective. One possible solution is to enhance the wired interconnects with short-range wireless communication (SRWC), which offers flexible resource allocation and the ability to broadcast data. However, implementing SRWC inside a computer chassis presents challenges due to multiple scattering. This scattering stretches the channel impulse response (CIR), leading to inter-symbol interference (ISI) and limiting data rates. To address this issue, we propose transforming…
