Multicell processing (MCP) techniques have attracted considerable research attention since they can effectively mitigate other-cell interference (OCI). However, the potential gain of MCP comes with several practical challenges including huge overhead and stringent synchronization requirements. In this paper, we propose cooperative opportunistic scheduling to coordinate OCI for downlink transmission...
In this paper, a block-by-block blind channel estimation algorithm is proposed for a multiuser orthogonal frequency division multiplexing (OFDM) system with an antenna array at the base station and a single antenna at each mobile unit. Provided that the channel is static within an OFDM block (i.e., block fading channel), based on the subcarrier averaging the proposed channel estimation algorithm can...
We propose a robust multi-mode linear precoder based on minimum bit error rate (MBER) selection criterion for multi-input-multi-output (MIMO) systems when transmitter only acquires the fading correlations of antennas. The key point of the scheme is that the number of substreams and modulation mode change adaptively to minimize the mean of BER by using channel correlation matrix. In addition, we analyze...
