Set the 4 SPS Laurent modulator to ignore the guard interval setting and always output 625 sample sized bursts. The EDGE 8-PSK modulator already has this behavior.

When EDGE mode is enabled for a particular slot, blind detection will be performed by correlating against EDGE followed by normal bursts if no EDGE burst is found.

Require 4 SPS sampling on both Rx and Tx paths as 1 SPS sampling adds too much distoration for 8-PSK recovery. Core receiver operations still run at 1 SPS with the exception of fractional delay filtering, which runs at the higher rate. Perform linear equalization to handle the Gaussian pulse induced ISI. The fixed impulse response used for equalizer tap calculation consists of combined EDGE pulse shape filter and effects of the downsampling filter. Note that the non-adaptive equalizer corrects for modulation induced band limiting and does not account for or compensate for fading channel effects.

Wider bandwith support is required on the receive path to avoid 8-PSK bandlimiting distortion for EDGE.
