MIMO detection and FEC belong to the most computationally complex parts of the receiver-side baseband signal processing chain. Implementations thereof must have low power consumption, but also be able to interact in a flexible and efficient way in the detection-decoding engine, while at the same time not compromising on the challenging throughput and flexibility requirements associated with 4G standards. In this paper, we present a chip implementation of a MIMO
