Orthogonal-Frequency-Division-Multiplex-Packet-Aggregation (OFDM-PA) for wireless network systems using error-correcting codes

摘要

A multiple-access communications downlink uses OFDM and error-correcting codes to send data to multiple terminals from a single access point, in which packets of message information for multiple users are aggregated and encoded into a single error-correction codeword, in which assigned time slots corresponding to specific OFDM symbols are used to separate different users, so that a near-capacity achieving channel coding system constructs a single codeword for use with iterative decoding architectures at the mobile terminals.
