A simultaneous packet transmission (SPT) technique is proposed to increase the throughput of a communication system. A SPT scheme employs multiple levels and employs multiple streams at each level above the first level. Every stream of the SPT has its assigned partition on the overall constellation. Symbols of an N ‐level SPT are formed by taking m i , bits from a selected stream of every i th level. The SPT scheme can employ higher code rates on streams at higher levels to increase the system throughput. Numerical results show that the SPT offers 15–30% throughput enhancement in turbo‐coded LTE systems.
