Modem crash with 10MHz channels

[dsilhavy]

Describe the bug Problem description by 5G-MAG RT user:

I’m working on a project using feMBMS. Due to the current lack of handsets we’re looking to use the 5G-MAG OBECA . The modem, middleware and gui/wui work really well until we use 10MHz channels (which causes the modem to crash). Is there anyone at 5G-MAG we can talk to to remedy this?

To Reproduce The behavior can be reproduced with the 10MHz sample files:

• RTP: https://obeca-testdaten.s3.eu-central-1.amazonaws.com/10MHz_MCS16_1kHz25_RTP_3.5.raw
• HLS: https://obeca-testdaten.s3.eu-central-1.amazonaws.com/10MHz_MCS16_1kHz25_HLS_q6a.raw

See: https://github.com/5G-MAG/Documentation-and-Architecture/wiki/Sample-Files

Expected behavior The Modem should be able to handle files with 10MHz bandwidth

Solution from @kuehnhammer :

- edit lib/srslte/lib/src/phy/phch/sch.c
- change #define CALCULATE_BER in line 34 to #undef CALCULATE_BER
- rebuild (cd build; ninja)

We should retest that after the srsRAN migration
