- The extended binary Golay code, or extended Golay code for short, is the essentially unique way to encode 12 bits of data in a 24-bit word in such a way that errors affecting up to 3 bits can be corrected, and errors affecting up to 7 bits can at least be detected. The easiest way to describe this code uses the geometry of the dodecahedron

The Golay code allows such systems to increase the probability of one-way, error-free, reception. Some communications channels are more prone than others to burst errors, where many consecutive data bits are corrupted. The Golay code is not alone able to correct bursts of errors over three bits long in a single codeword The extended (24, 12) binary Golay code considered in this submission can correct three or fewer errors. Due to the 11 x 11 matrix Bc, having a cyclic structure and being a component of both the generator and the parity check matrices of this code, its decoding procedure is very simple Golay figured out the optimal code for 23 bits, called the Perfect Binary Golay code, but often, one extra bit is added, to get the 24 bit Extended Binary Golay Code. This one is in fact a little more wasteful, but its relation to symmetry is more clear.

The length of the Golay code excitation is taken into account twice since two series must to be used. Golay codes in low-power laser-ultrasonics are normally applied with a length of ≫2 7 = 128, therefore it can be assumed that L ≫ β > 1, hence: (25) Δ = L + β L ( 1 + β) ≈ 1 1 + β Under the Golay sequence-coded excitation, the code lengths were respectively 4 bits, 8 bits, and 16 bits. The signal-to-noise ratio increased linearly with increasing length of the excitation code * Ultrasonic Testing (UT) is one of the most important technologies in Non-Detective Testing (NDT) methods*. Recently, Barker code and Golay code pairs as coded excitation signals have been applied in ultrasound imaging system with improved quality. However, the signal-to-noise ratio (SNR) of existing UT system based on Barker code or Golay code can be influenced under high high attenuation.

An algebraic description of the erasure channel is given and a nearest neighbor decoding scheme is defined. This decoding scheme is viewed as a standard array decoding by suitably partitioning the set of received words. The analysis of this partition leads to the study of punctured.
