%X <span class="fontstyle0">In this paper, a new spatial quadrature modulation ( NSQM ) scheme is proposed to improve the error<br>
performance of indoor visible light communication ( VLC) systems. NSQM is different from generalized spatial<br>
quadrature modulation ( SQM) in two aspects. First, the transmitted optical signal is directly detected at the<br>
receiver, which does not need to estimate the indices of the transmitted antenna. Second, an optimization approach<br>
is used with NSQM to minimize the upper error bound of the transmitted signals. In addition, several NSQM<br>
schemes are described in detail. Numerical results show that the proposed NSQM scheme achieves superior error<br>
performance compared with the SQM scheme.</span> <br>
