Abstract

This paper describes a VLSI implementation of BLAST detection for MIMO-OFDM systems. To achieve high speed requirement, we propose the fully pipeline architecture for BLAST structure. This design is implemented using $0.18{\mu}m$ CMOS technology. For a 4-transmit and 4-receive antennas system, it takes $7.5{\mu}s$ to calculate nulling vector and detection order from 48 channel matrixes.
