Andre Puschmann 9149cf852d rf_uhd: fix rx timeout error after late with B210 
it fixes #1623.

this happens more often with MIMO since lates are more likely here.

after a late, the Rx stream must not be stopped on the B2xx either.

Andre Puschmann 5e40bfe72c mac_pdu: unpack and print BSR index as well as BSR value in bytes 
before the BSR was extracted but the actual index (between 0 and 63)
was not stored but directly converted into bytes.

for log parsing and debugging it is easier to follow the index
value. this patch therefore adds both values to the log message
and extends the API accordingly.

faluco 072e84cec8 - Simplified the usage of span now with implicit constructors as it should be. 
- Added overload for generic containers that have size and data members like vector.
- Removed unnecessary uses of make_span.
 2020-08-11 19:47:26 +01:00
faluco 158edd4fe7 Removed init list constructor test. 2020-08-11 19:47:26 +01:00

- Fixed compilation failures in tests.
 2020-08-11 19:47:26 +01:00
faluco af8dfcf19c Extended a bit the span implementation with the following changes: 
- Documented methods and class.
- Adapted interface to the latest standard: no init list and generic container constructors, new iterator pair ctor.
- Implemented some SFINAE for managing conversions in constructors.
- Re-organised some methods to be grouped by category (modifiers, observers, iterators, ...).
- Added convenience make_span functions.
- Added some more  asserts.
- Adapted test to use some syntax that was modified.

Andre Puschmann 5867668c0c rf_uhd_rfnoc: fix compilation for UHD before 3.15 
the enable_rx_timestamps() for the radio_ctrl object has only been
introduced in Nov 2019 for UHD 3.15 and therefore needs
to be excluded when compiling for 3.14 and below.

Note: According to the original UHD commit in
67dbaa41f2 (diff-60a9387c0fc8406fd5b39fa995dd8c14)
it looks like the Rx timestamps are disabled by default
for UHD versions before 3.15

This commit fixes #1602

Andre Puschmann d441486f76 fading: fix heap buffer overflow in fading sim 
at the when applying the fading channel we copied the state back
to our buffer. Since we are offsetting the read buffer
by X samples, we need to make sure that we don't read after then
(len-X) samples of the temporary memory buffer

Andre Puschmann 1199a79851 fix Scell sync for large cells 
the PSS detection needs more temporary buffer than a full subframe.
we therefore need to allocate and initialize the sync object with
larger maximum size to support Scell search of large cells, e.g.
20 MHz
