A fault-tolerant modulus replication complex FIR filter

In this paper we propose an architecture for the implementation of fault-tolerant computation for a high throughput multirate equalizer used in a 1 Gbps asymmetrical wireless LAN. Exploiting the algebraic structure of the modulus replication residue number system (MRRNS) minimizes the area overhead, and the area cost to correct a fault in a single computational channel is 82.7%. Generalized results for single error correction showing significant area savings are also presented.
