FRAME BIT DETECTOR IN NEAR FIELD COMMUNICATIONS |
摘要 |
Described herein are architectures, platforms and methods for (NFC) frame bit detection. A frame bit detector includes a sample-based bit detector that receives samples which may be data and non-data (noise), identifies data bits at every sample input time, and the likelihoods that the identified data bits are part of data. The frame detector includes a maximum likelihood frame detector configured to receive bits from the sample-based bit detector and the likelihood of each bit that the bit is data, and calculate frame likelihood. |

1. A near field communication (NFC) enabled device comprising:
an NFC receiver comprising an frame bit detector comprised of: a sample-based bit detector configured to receive demodulated samples obtain from data and non-data, identify data bits at every sample input time, and the likelihoods that the identified data bits are part of data; and a maximum likelihood frame detector configured to receive bits from the sample-based bit detector and the likelihood of each bit that the bit is data, and calculate frame likelihood. |
