BPSK Matched Filter Discovery Matched Filter: Step-by-Step How do we find a "1" inside a mountain of noise? Let's break it down. 1. Data Input (Bits) 2. Channel Noise (SNR) 5 dB 3. Filter Shape Sine Wave (Standard) Square Pulse STEP 1: The Template To recognize a signal, the receiver needs a "Search Image" (The Template). We create one perfect cycle of our carrier wave. Logic: If the incoming signal matches this shape, the math will result in a MAXIMUM PEAK . STEP 2: The Noisy Reality Here is your data sent over the air. We added Random ...

Rank & Condition Number FAQ What is the "Rank" of a wireless channel matrix mathematically? Mathematically, the Rank of a matrix $H$ is the number of linearly independent rows or columns. In your simulator, it is found by performing Singular Value Decomposition (SVD) and counting the number of non-zero singular values ($\sigma$). If a $4 \times 4$ matrix has a Rank of 2, it means only two "paths" are truly independent. How does Channel Rank apply to MIMO systems? In MIMO (Multiple-Input Multiple-Output) , the Rank defines the maximum number of independent data streams (spatial multiplexing) you can send simultaneously. A Full Rank channel is ideal because it allows for the highest possible data rate by using all available antennas for different data layers. ...
