Thomas Schlichter 5c6865fbc6 5G NR: simplify init_timeshift_rotation() 
Only Ncp1 is used, so get rid of the second timeshift_symbol_rotation array.
Also simplify the computation of "t0 * Tc * f".

Sakthivel Velumani 945a020f93 Added linear phase derotation in UL 
This is necessary to compensate the rotation caused by the timeshifted OFDM symbol (1/8 CP)

Thomas Schlichter 87b53883b2 HACK: cut PUSCH and PDSCH OFDM symbol after complete CP 
Currently we cute the PUSCH and PDSCH OFDM symbols starting within the last 1/8th of the CP to avoid ISI.
This time shift leads to a rotation in frequency domain.
The current PRB based channel estimation does not compensate for the rotation _within_ a PRB, leading to bad performance.

This commit should _not_ make it into develop branch, it is just for testing!
Instead, we should do some compensating rotation before channel estimation.
