Various scenarios are considered where some information is more important than other and needs better protection. A general theoretical framework for unequal error protection is d...
In this paper, we study power allocation (PA) in a single-relay OFDM system with limited feedback. We propose a PA scheme that uses a codebook of quantized PA vectors designed offl...
Abstract. This paper compares two approaches to reliable communication over fading channels using low-density parity check (LDPC) codes. The particular model considered is the bloc...

1 In this paper, we consider a downlink communication system, in which a base station (BS) equipped with M antennas communicates with N users each equipped with K receive antennas....
— Precoding is a well-known method to reach the promised performance and capacity of multiple-input multipleoutput (MIMO) systems. Recent investigations, when the transmitter has...
