Other/Summer/2024/pMA

-              v14
+              v15
      - Created custom python blocks to interact with OFDM Carrier Allocator Block:
             - Prints its output in a readable format.
             - Multiplies specified carriers by precoded vector.
      - Studied the math that goes into Symbol Precoding.
+            - Multiplies *specified* carriers by precoded vector.
+     - Studied the math that goes into Symbol Precoding vector calculation.
      - Began implementing these functions using Python so we can complete our system and begin testing.
+     - After finishing the Precoding Calculation functionality we brought it into GNU Radio as a custom block and fixed many bugs.
 **Week 5 (6/24 - 6/27)**

+**Week 6 (7/1 - 7/03)**
+     - Spent many hours comparing output of Hari's matlab code with our new GNU Radio block's output to ensure correct precoding calculations.
+     - Created an Emulator block for testing which would simulate the effects of the antenna on our signal digitally.
+     - Created a Power Control block to ensure that we do not supply a dangerous voltage to our Metamaterial Antenna when we begin real world
+       experiments.
+**Week 6 (7/1 - 7/3)**

+     - Modified our custom Python blocks to ensure consistent processing of chunks. This was an issue as a couple of the blocks were processing
+       more data than needed at once, causing downstream blocks to halt unnecessarily.
+     - Hari informed us that our method of utilizing sync words might have been misguided, and we reorganized our flowgraph to reflect
+       these changes. This involved removing sync words from our precoding vector calculations and prepending them to the output.
+     - Researched the Sychmidl and Cox synchronization method.
