Bit overhead for tag acquisition under perfect conditions. The dashed lines depict the FSA-based schemes, while the solid lines depict the CS-based schemes (e.g., Buzz, CSF, see [9–14]). By exploiting our novel approach with the BASSAMP algorithm, we are able to reduce the bit overhead of CS-based schemes by a factor of 2.2 (N R =1) respectively 3.3 (N R =4) over the legacy AMP algorithm. Overall, the CS-based schemes strongly outperform the FSA-based schemes, despite collision recovery methods [8] that utilize several antennas
