WIRELESS DEVICE AND TRAINING SIGNAL TRANSMISSION METHOD |
摘要 |
<p>The number of OFDM symbols for channel estimation is reduced, overhead due to a pilot signal and a feedback signal is reduced, and the throughput is improved. A wireless apparatus is provided with: an iterative coefficient setting unit which sets, for a plurality of transmission ports, an iterative coefficient representing the number of transmission ports which share a plurality of frequency channels of training signals for estimating the channel information; a training signal generating unit which allocates frequency channels to each transmission port so as to satisfy the set iterative coefficient and generates L training signals based on the allocated frequency channels; a channel information acquiring unit which acquires channel information estimated from the training signals from a communication partner for the frequency channels allocated to each transmission port; and a channel information interpolating unit which interpolates channel information of a remaining frequency channel other than the frequency channels allocated to each transmission port from the acquired channel information.</p> |
