Given the M-PSK signal constellation, (|ℎ 1 | 2 + |ℎ 2 | 2 − 1)|𝑥 𝑖 | 2 , 𝑖 = 1,2 , is a constant for all signal points with respect to the fading channel coefficient. Therefore, the decision rule in (3.8) and (3.9) is simply as follows: 2 𝑥 1 = arg min 𝑥 1 ∈ 𝑆 𝑑 (𝑥 ...
The complexity of the D-BLAST architecture makes it difficult to implement. In 1996, Wolniansky together with Foschini, Golden and Valenzuela proposed the V-BLAST architecture, which was implemented in real time at Bell Laboratories with the first bandwidth performance of up to 20-40 bps/Hz at ...
Transmitter station Line 1 Line 2 α 1 v Reflective object Figure 2.11. Transfer function of 2.5.3. AWGN noise AWGN noise exists in all transmission systems. The main sources of noise are thermal noise, electromagnetic noise from receiver amplifiers, and inter-cell noise. These types of noise can ...
