Gr-baz

General

NOTE: A few components will not work (e.g. BorIP client) without applying certain patches to your GNU Radio source. Please see below.

The module name is baz, so in Python one would write:

baz.<block>(args)

To import a file (e.g. borip):

from baz import <file>

patch

Before using various blocks in gr-baz, you must apply at least some of the patches contained in this directory to your GNU Radio source tree. For example: you must update gr_udp_source if you wish to use it as a BorIP client.

lib (C++)

delay

Unlike the original gr_delay block that has a fixed delay, this allows for a variable delay that can be changed at runtime. The delay can be positive or negative. If any padding is required, it uses the value of the last sample.

grc

GRC XML block definitions for:

• agc: AGC (Baz) - this is unfinished
• auto_fec: Auto FEC
• borip_source: BorIP Source
• delay: Variable Delay
• puncture_bb/depuncture_ff: Puncture/Depuncture
• pow_cc: Power
• swap_ff: Swap
• test_counter_cc: Test Counter
• eye: Eye Diagram
• facsink: Fast AutoCorrelation Sink
• gr_mpsk_receiver_debug_cc: MPSK Receiver (Debug)
  • Requires appropriate patch to gr_mpsk_receiver_debug.cc

Also, this contains patches for GRC to enable 'any' block support. This enables you to use raw GNU Radio blocks by typing in the necessary Python function to create the block (without a dedicated GRC XML block definition). For example: I use it with baz.print_char

• baz_any_source: Any Block Source (for source blocks)
• baz_any_sink: Any Block Sink (for sink blocks)
• baz_any: Any Block (for blocks with I/O)

You can either apply the following two patches, OR apply one from the patch page:

• Block.py.diff
• Port.py.diff

apps

am_fft

Same functionality as usrp_fft.py, however the AM (magnitude) signal is shown instead of the original complex one.

usrp_fac

Stand-alone app for using the Fast Auto-correlation Sink.
