  • Abstract
    The effects of hangup in digital asynchronous timing recovery loops are investigated. It is demonstrated that delay quantisation in the interpolation filter exacerbates the problem of hangup. It is also noted that the effects of hangup are worse for the non-data aided (NDA) loops than they are for the decision-directed (DD) loops. This may preclude the use of the former in TDMA applications.
