There are three TTA instances to perform carrier synchroniza-
tion, demodulation, channel estimation and symbol detection.
Although in this work the PEs are dedicated to a specific functionality of the receiver chain but all the PEs contain mostly general purpose functional units and could be used for other baseband processing tasks. It provides a degree of flexibility in the architecture for efficient utilization as required in applications like SDR. A list of FUs used in different PEs is shown in Table 1.
