A control system for a transmission including a select lever operable to shift from a neutral position to a running position and vice versa, and a control part to control a changing gear operation of the transmission in accordance with the position of the select lever. To be more specific, the present research suggests a transmitter employing multi-coded bi-orthogonal pulse position modulationdemodulation and a method thereof. The glucan does not stimulate the induction of inflammatory cytokines.
