In this paper, we investigate the achievable uplink spectral efficiency (SE) and its approximate analytical expression in massive multi-input multi-output (MIMO) systems, using finite precision analog-digital converters (ADCs) and zeroforcing (ZF) technique at the receivers. To analyze the system performance, we adopt the additive quantization noise model, where the quantization noise is treated as...
In this paper, we investigate the link-level simulation of the time-division-duplex (TDD) based massive MIMO system employing OFDM technology. Influenced by the hardware mismatch between base station (BS) and mobile stations (MS), and the limitations of hardware implementation, the system model, simulation settings, and simulation procedures for uplink (UL) and downlink (DL) are presented to help...
In this paper, we consider the problem of pilot based data transmission in massive multiple-input multiple-output (MIMO) systems where each receiver antenna is equipped with a low-precision analog-to-digital converter (ADC). Under the quantized MIMO setting, we derive a tight approximation of the uplink spectral efficiency considering a maximal ratio combining receiver. Capitalizing on the derived...
