Abstract
A system and method for multiplexing subchannels in an OFDMA network is provided. The subchannels can be multiplexed by splitting the subchannels in the frequency domain. Alternatively, the subchannels can be code division multiplexed using N orthogonal spreading codes. The subchannel multiplexing increases system capacity for low-rate services, such as voice-based services.
