After deinterleaving, all of the values of [y.sub.i,j], for 0 [less than or equal to] i [less than or equal to] N - 1 and 0 [less than or equal to] j [less than or equal to] M - 1, are input to "erasure insertion." This block erases several symbols with a selected rule, which will be described in Section 3.
Next, we briefly introduce the three conventional erasure insertion schemes: the ratio threshold test (RTT), the output threshold test (OTT), and the maximum output-ratio threshold test (MO-RTT) [4-7, 25].
Threshold test-based conventional schemes have used the one-time erasure insertion and the bounded-distance decoding with preoptimized thresholds.
If the decoder declares a decoding failure, it erases the most suspicious (likely to have been jammed) symbol [mathematical expression not reproducible] and replaces it with an erasure e, where [i.sub.max] is determined by the selected decision rule.

Mining multiple connotations of erasure
, from the theoretical to the autobiographical, Simmons keeps us from forgetting what can't be erased: the limits of narrative.
However, Derrida extended the problem of presence and absence to include the notion that erasure does not mark a lost presence, rather the potential impossibility of presence altogether (Derrida 1967).
The erasure of girlhood in the context of patriarchal power
Using the characters Tambu in Dangarembga's Nervous Conditions, Miriro and Tariro in Hove's Ancestors, Janifa in Hove's Bones and Vaida in MahachiHarper's Echoes in the Shadows, this section will engage with the apparent erasure of girlhoods by the patriarchy.
