Sorry, the Encode / Decoder is designed for desktop use only. Please, check our dCode Discord community for help requests!NB: for encrypted messages, test our automatic cipher identifier! VP7. (1) Find the generator matrix G ,and parity check matrix H. (2) Decode the following received vectors on a binary symmetric channel (with a crossover probability < 1 / 2) by using syndrome decoding: 1 = ( 01101011), 2 = ( 00010110). This is because you must have an even number of characters, because of how the encryption works (in groups of two letters).When the letters are changed to numbers, my message reads as:19,5,14,4,0,8,5,12,16,0But remember, we are doing this with matrixes and letters in groups of two, so it will be better if you write it in this format:[19 5] [14 4] [0 8] [5 12] [16 0]. The elements in blue are the scalar, a, and the elements that will be part of the 3 3 matrix we need to find the determinant of: Continuing in the same manner for elements c and d, and alternating the sign (+ - + - ) of each term: We continue the process as we would a 3 3 matrix (shown above), until we have reduced the 4 4 matrix to a scalar multiplied by a 2 2 matrix, which we can calculate the determinant of using Leibniz's formula. Matrix calculations with complex numbers are also supported. Next, we can determine the element values of C by performing the dot products of each row and column, as shown below: Below, the calculation of the dot product for each row and column of C is shown: For the intents of this calculator, "power of a matrix" means to raise a given matrix to a given power. Most calculations use tools such as the determinant of the matrix, or the matrix inverse calculations. (2) Decode the following received vectors on a binary symmetric channel (with a crossover probability $ 1/2$) by using syndrome decoding: $$ _1 = (01101011),\, _2 = (00010110).$$ (3) Decode again using the maximum-likelihood decoding. Taking into account that you need to decode the same FPS as you encode lets look at the GTX 1070; It supports NVENC h.264@1262 FPS but only NVDEC h.264@658 FPS, this would mean 658 FPS@1080p is the maximum throughput with a single pass encoding profile, not the full 1262 FPS. To decrypt hill ciphertext, compute the matrix inverse modulo 26 (where 26 is the alphabet length), requiring the matrix to be invertible. Product and either saves the values or prints them out can use fraction button. The encoding requires 2 steps: High level encoding: consists in the conversion in codewords of the data, adding some stuffing codewords and calculating the checksum one; Low level encoding: consists to position these codewords in the data matrix.
