Joint Cell Selection and Resource Allocation Games with Backhaul Constraints
Jorge Ortin, Jose Ramon Gallego, Maria Canales
In this work we study the problem of user association and resource allocation to maximize the proportional fairness of a wireless network with limited backhaul capacity. The optima…
A* Based Algorithm for Reduced Complexity ML Decoding of Tailbiting Codes
Jorge Ortin, Paloma Garcia, Fernando Gutierrez +1
The A* algorithm is a graph search algorithm which has shown good results in terms of computational complexity for Maximum Likelihood (ML) decoding of tailbiting convolutional code…
Channel Independent Precoder for OFDM-based Systems over Fading Channels
Jorge Ortin, Paloma Garcia, Fernando Gutierrez +1
In this paper we propose an independent channel precoder for orthogonal frequency division multiplexing (OFDM) systems over fading channels. The design of the precoder is based on…
Performance Analysis of Turbo Decoding Algorithms in Wireless OFDM Systems
Jorge Ortin, Paloma Garcia, Fernando Gutierrez +1
Turbo codes are well known to be one of the error correction techniques which achieve closer results to the Shannon limit. Nevertheless, the specific performance of the code highly…
Two Step SOVA-Based Decoding Algorithm for Tailbiting Codes
Jorge Ortin, Paloma Garcia, Fernando Gutierrez +1
