Glitch mitigation in a radio receiver |
| 摘要 |
A basic idea is to determine (S1) occurrence of a glitch caused by operation of the AGC mechanism, identify (S2) those modulation symbols in a digitized version of the received signal that are affected by the glitch, each modulation symbol represented by a number of bits in combination, and then reduce (S3), for each of the identified modulation symbols, the contribution in representing the identified modulation symbol as provided by at least a subset of the bits of the modulation symbol. In this way, the adverse effects of the glitch can be effectively mitigated and subsequent detection of the desired signal can be significantly improved. This also means that the link performance will be significantly improved. |

1. A method for glitch mitigation in a receiver having an automatic gain control (AGC) mechanism for regulating a dynamic range of a received signal, comprising:
determining occurrence of a glitch caused by operation of the AGC mechanism; identifying those modulation symbols in a digitized version of the received signal that are affected by the glitch, each modulation symbol represented by a number of bits in combination; and reducing, for each of the identified modulation symbols, a contribution in representing the identified modulation symbol as provided by at least a subset of the bits of the modulation symbol.
