Correction is not possible with one parity bit since any bit error in any position creates exactly the same information as bad parity. If more bits are integrated ...

図2.13から分かるように、距離が3のコードワード間では、2ビットのエラーが起こると隣のコードワードを囲む1ビットエラーの球に入ってしまう。そして、受信されたデータに対してシンドロームを計算して訂正を行うと、 2ビットのエラーが起こったコード ...

Error Correction Codes (ECC) play an essential role in safeguarding memory systems by detecting and correcting errors that arise from various sources, including ...

FEC (forward error correction), a critical component of many modern digital-communications applications, turns otherwise-unusable links into real and practical ...

Second, the codes are typically 7 or 8 bits, which makes for an inefficient use of a 16-bit memory structure. This is handled by using the same memory chip for data and codes. This is referred to as ...

As with any electronic system, errors in the memory subsystem are possible due to design failures/defects or electrical noise in any one of the components. These errors are classified as either ...

Whenever we send data — whether it’s audio signals over a phone line, a data stream or a legal document — to someone else, we need to know that what arrives on the other end is identical to what we ...
