small bugfix for missing initialization

49. By Jan on 2012-09-01

small fix for 32bit compilation

48. By Jan on 2012-07-01

Some fixes and a couple of new features:

MU-MIMO Scheduler variants:
* PU2RC
* Zero Forcing based on quantized low bitrate PU2RC feedback

3GPP TR 36.829 Wishart-model based spatial covariance estimation error model for the evaluation of "advanced receivers" (e.g., MMSE-IRC)
- further options to distinguish between intra and inter-cell interference covariance estimation

More probing features in the linear receiver including mutual information rate computations and SINR/IoT deviation probing

PF schedulers take an additional parameter to add a history weighting exponent to the PF metric

Option to fix the feedback (and thus the scheduling) cell-wide to a single PMI per PRB

47. By Jan on 2012-04-16

Some minor changes:
- enabling BLER/HARQ adaptive outer-loop DL link-adaptation by default for non-RR schedulers
- minor improvement to static non-outer-loop DL link-adaptation
- downlink feedback manager can be derived from
- added more power control capabilities to downlink (resource manager etc.)

better PMI feedback for rank-1 precoding

44. By Jan on 2012-04-02

- max rank for MMSE receiver configurable
- downlink feedback manager interface added -> can now be replaced by pyconfig
- made clear distinction between estimated and perfect uses of channel and I+N covariance matrices in LinearReceiver
- added interface and different options for channel and I+N covariance estimation error models:
     * channel: additive Gaussian noise matrix, colored or white Gaussian noise matrix according to I+N covariance
     * I+N covariance: perfect I+N covariance, equal diagonal, diagonal only, with additive Gaussian noise matrix
- removed getInterferenceLevel method from Receiver; use I+N covariance estimation instead
- changed MKL Gaussian RNG options for lsParams -> speedup especially for RMa
- transmit powers can be configured differently per PRB for each transmission
- unit test for LTE 4 Tx antenna Codebook (codebook was correct before)

43. By Jan on 2012-03-14

- Added 3GPP TR 36.814 antenna configurations A, B, C, D, and E with support for angle-independent antenna polarization (A.2.1.6.1)
- fixes for two transport blocks in spatial multiplexing transmission
- reduced BLER LUT range
- added copying of TBs to retransmit (again)
- better tracing for multi-layer transmission
- fixed return type problem in full queue that triggered problem with PF scheduling
- added frequency-domain RR scheduling option for downlink
- more SM probes
- better SM Feedback

merge from maciej - thanks for the FullBuffer queue

Merged branch lp:~mue-comnets/imtaphy/fullBuffer

41. By Jan on 2012-03-09

- fixed a bug in transport block to layer mapping for rank 4 transmission
- added resolution for both streams (parallel transport blocks) in BLER probe
- fixed a problem for handling of two transport blocks in HARQ entity
- made queues always accept but drop packets if full to allow recording offered traffic in probe above
- internal interface changes
- more MIMO related probing
