Release 1.1.0 - Q4 2021

Downlink Support added for hardware
General Bugfix support
Mac works with hardware uplink with 1 user (video data demo)

• better verbosity in initial calibration

• use single gain in json

• modify retries for calibration

• Added some helper text

• Switching to udp

• Add Core-Thread Allocation Summary

• Increase number of data streams (need to add variable)

• Files ready for testing. Mac UDP packet size < max

• Debugging updates. Fixed a few indexing issues.
  Tested with MacSender not running (looks ok)
  Tested with MacSender running in UDP mode with no data availble (looks ok)

• Tested with the FileReader with full packets and fixed size partial packets. Looks good for 1 user.

• print UL and DL bit rates in config

• Added hooks for stream #2

• Fixed error setting initial core offset

• disable RBIndicator

• Config file changes to sync updates

• Updated the e2e test parameters because the sim send rate increased

• Pushing a sim mac configuration similar to the operational hardware configuration

• Removing alignment of the mac packets, since they are just a grouping of bytes after decoding.

1. Readability improvements for the mac packets
2. Removed the padding, and extra variables that enforced alignments.

• Added core assignment summary to end

• reducing the thread core footprint

• Fixed an offset issue with the mac packet

• Synced basestation and user mac thread updates

• Fixed output and tested with the channel sim in AWGN mode

• added memory alignment check

• Switched around the TX scheduling to match socket thread expects

• Modified the core assignment logic to wrap around and exclude a core list.

• Added core exclusion list

• Allow pinning same thread to same core

• Use int type for rx_offset in the sync process

• Matlab script to analyze down-link data recorded in ue_worker

• More verbose errors in initial calibration!

• Print pilot SNR range (across antenna) for each user

• Fix bug in radio_id calculation for two channel scenario.

• Functions to save armadillo matrices and vectors to file.

• Add a separate moving sum calibration buffer

• Set initial calib buffer to one.

• Fix bug in passing calib buffer argument to DoZF and PacketTXRX.

• Turn off initial calib by default

• Better boolean naming for recording frame index

• Fix dual-channel downlink seg fault by using UeAntNum instead of UeNum in PhyStats

• Set calib vector values for first few frames to one when initial calib is off. Print ZF matrix condition number.

• Fixed indexing issue (keeps incrementing)

• Print reciprocal calibration pilot SNR stats

• Fix bug in dual-channel UE pilot TX scheduling

• Move ZF condition number updates to PhyStats

• Send uplink calibration symbol in txrx instead of FPGA buffer.

• sw/hw framer mode for base station

• Modified the config to allow larger frames in hardware

• Disable rcond calculation by default.

• Fix error for using AVX2 FlexRAN on AVX512 capable machine

• Allow DPDK to select NIC with given MAC addresses

• Load iris serials from json. Unify bs and ue configs.

• Remove deprecated reciprocal test

• Fix uplink breaking due to incorrect Direction setting

• Fix bad indexing for ref radio

• Fixed memory leak upon program exit

• Change Channel to UeChannel for clients

• Better handling of reference nodes

• Fix ref radio bug

• Fix handling of reference node in uplink-only mode.

• Updating the e2e test to align cores on falcon

• Modified UeNum to UeAntNum on the basestation side

• Separate Function for Reciprocal Calib functions

• updated powder configs (ul and dl)

• Added additional retries on all ::make calls

• Use single JSON config in channel simulator

• Fix out of bound rx buffer offset

• Pick last peak in FindBeacon

• Disabled untested configurations
