Design of Discrete-time Matrix All-Pass Filters Using Subspace Nevanlinna Pick Interpolation
Agulla Surya Bharath, Devanshu Singh Gaharwar, Kumar Appaiah +1
Unitary matrix-valued functions of frequency are matrix all-pass systems, since they preserve the norm of the input vector signals. Typically, such systems are represented and anal…

A Post-coder Feedback Approach to Overcome Training Asymmetry in MIMO-TDD
Arun Kumar Miryala, Irina Merin Baby, Kumar Appaiah +1
Time Divison Duplex (TDD) wireless communication systems are inherently bidirectional, which facilitates exploiting channel reciprocity for pilot based channel estimation of both u…
