After 3 month of coding and altogether over 4 month since my first proposal for GSoC, I want to look back to this wonderful experience. Continue reading “At the end…”
This blog post delivers a short summary of the work that was done during the GSoC’18 program. Continue reading “Final Week – Summary of the Project”
As I described in my last blog post, we changed the structure of the receiver.
This week, I intensively worked on the implementation of the additionally required signal processing blocks. All in all, the blocks are finished now, but there is still a lot of testing to be done. Continue reading “Week 12 – Generalizing the MIMO algorithms to a vector basis.”
After discussing the proposed MIMO-OFDM receiver structure (see post of last week) with my mentors this week, we decided to do some major changes in the structure of the receiver to meet some general requirements. Continue reading “Week 11 – Final Receiver Structure”
After finishing the MIMO-OFDM transmitter last week, I approached the receiver this week and thought a lot about its structure. Before I want to propose a structure for the MIMO-OFDM receiver, let us first have a look at the current SISO-OFDM receiver: Continue reading “Week 10 – Designing the MIMO-OFDM Receiver”
I successfully finished the MIMO channel estimator this week. The corresponding qa test is also finished and running. I therefore completed all elements which are required to build up the hierarchical python blocks of the MIMO encoder and decoder. Continue reading “Week 09 – Hierarchical MIMO Encoder Block”
I implemented a MIMO channel estimator this week.
The purpose of a channel estimator is the estimation of the channel state information (CSI) which is required for many MIMO algorithms. The goals for such an estimator are a small estimation error but also a low estimation complexity and a small proportion of training data in comparison to the actual payload. Continue reading “Week 08 – Channel Estimation”
