A Reinforcement Learning Framework for Resource Allocation in Uplink Carrier Aggregation in the Presence of Self Interference
Jaswanth Bodempudi, Batta Siva Sairam, Madepalli Haritha +2
Carrier aggregation (CA) is a technique that allows mobile networks to combine multiple carriers to increase user data rate. On the uplink, for power constrained users, this transl…
MIMO-Zak-OTFS with Superimposed Spread Pilots
Abhishek Bairwa, Ananthanarayanan Chockalingam
In this paper, we consider the problem of spread pilot design and effective channel estimation in multiple-input multiple-output Zak-OTFS (MIMO-Zak-OTFS) with superimposed spread p…
Delay-Doppler Pulse Shaping in Zak-OTFS Using Hermite Basis Functions
Fathima Jesbin, Ananthanarayanan Chockalingam
The performance of Zak-OTFS modulation is critically dependent on the choice of the delay-Doppler (DD) domain pulse shaping filter. The design of pulses for is co…
A Hybrid I/O Relation Estimation Scheme for Zak-OTFS Receivers
Sai Pradeep Muppaneni, Vineetha Yogesh, A. Chockalingam
In this paper, we consider the problem of estimating the delay-Doppler (DD) domain input-output (I/O) relation in Zak-OTFS modulation, which is needed for signal detection. Two app…
