d max | Maximum diversity order that can be achieved by any code for a fixed m s and m r |
t min | Minimum number of times that a source is included in the transmission set of any relay |
d R | An upper bound on the diversity order d, d R = 1 + tmin |
n | Is equal to in the case that is fixed by the protocol and thus constant |
m | Represents m s and m r when m r = m s |
M | Coding header indicating the presence of the source codewords in all transmissions; depends on |
| Set, collecting the indices of the blocks that are erased in the case of the BBEC |
| Reduced coding header obtained from M where all erased transmissions have been removed |
| Collection of all possible matrices when |
| Rank of |
d M | In some cases, d M , which depends on M, is an upper bound on the diversity order d |
