As a linear subspace of , the entire code C (which may be very large) may be represented as the span of a set of codewords (known as a basis in linear algebra). These basis codewords are often collated in the rows of a matrix G known as a generating matrix for the code C. When G has the block matrix form , where denotes the identity matrix and P is some matrix, then we say G is in standard form. WebNov 8, 2024 · Details.
