Correct Bluetooth EDR FEC Performance with SEC-DAEC Decoding
نویسندگان
چکیده
R. Razavi, M. Fleury and M. Ghanbari By selecting from Bluetooth’s Enhanced Data Rate (EDR) packet types according to channel conditions, optimal data-rates are approached, especially if Forward Error Control (FEC) is extended to EDR. This Letter presents correct calculation of these packet types, which also accounts for Double Adjacent Error Correction (DAEC) in addition to conventional Single Error Correction (SEC).

Analytical Approach For Decoder Delay Reduction Sec-DED- DAEC Codes Derived From Orthogonal Latin Square Codes
Although tremendous progress has done in past years on memory designing but still Radiation-induced soft errors is concerned area in the field of soft memories and the single error correction double error detection (SEC-DED) codes are commonly used to give assured memory contents with absence of corrupted scenario. Since SEC-DED codes cannot correct multiple errors, they are often combined with...
متن کاملImproving Bluetooth EDR Data Throughput Using FEC and Interleaving
Wireless communication is inherently vulnerable to errors from the dynamic wireless environment. Link layer packets discarded due to these errors impose a serious limitation on the maximum achievable throughput in the wireless channel. To enhance the overall throughput of wireless communication, it is necessary to deploy link layer transmission schemes that is robust to the errors intrinsic to ...

The Bluetooth radio multipath, fading indoor channel with Additive White Gaussian Noise (AWGN), was evaluated by simulation using a component-based architecture to model the Physical layer. The communication model included Forward Error Correction (FEC) and Automatic Repeat Request (ARQ) schemes. The observed Bit Error Rate (BER) versus Signal:Noise Ratio (SNR) using AWGN and a statistical chan...

In digital video broadcasting-handhelds (DVB-H), the contents to be transmitted come in the form of internet protocol (IP) datagram, which are passed to the multi-protocol encapsulation with forward error correction (MPE-FEC) entity. MPE-FEC employs erasure Reed-Solomon (eRS) error correction combined with cyclic redundancy check (CRC), is defined in standard. However, a critical factor must be...
متن کاملAutomatic Keyword Extraction from Spoken Text. A Comparison of Two Lexical Resources: EDR and WordNet
Lexical resources such as WordNet and the EDR electronic dictionary (EDR) have been used in several NLP tasks. Probably partly due to the fact that the EDR is not freely available, WordNet has been used far more often than the EDR. We have used both resources on the same task in order to make a comparison possible. The task is automatic assignment of keywords to multi-party dialogue episodes (i...
