Different types of pilot symbols used in MIMO channel estimation are described in [15].
In [7], the authors proposed an estimator employing a specific pilot structure consisting of two types of pilot symbols with different pilot densities.
The direct-detected optical OFDM (DDO-OFDM) system in frequency-selective fading fiber channel with three different types of pilot interval design has been experimentally investigated.
Three types of pilot-scale RDBs, a single-layer RDB, a multi-layer RDB, and a hybrid RDB, were examined at various gas EBCTs but at a constant VOC loading rate.
The goal is that, by scaling up these types of pilot projects, utility-managed EV charging can assist China's power sector to move towards the goals outlined in the NEA's work plan: a flexible electricity grid and a diverse set of uses for China's renewable energy resources.
Other types of pilot studies such as feasibility studies for randomized trials would be ideal in terms of integrating REA.
Two types of pilot scale (100 × 150 m) free water surface constructed wetlands were set up at the Royal Laem Phak Bia Environmental Research and Development Project in central Thailand.
On 2 October 2007, the Federal Energy Regulatory Commission held a workshop in Portland, Oregon, where it proposed a program to complete licensing for several types of pilot projects within six months.
Although this type of pilot allocation simplifies the channel estimation, it presents some drawbacks.
