Tone allocation in multipoint-to-point communication using orthgonal frequency division multiplexing
Patent number: 7355963Abstract: Systems for tone allocation are provided. In one embodiment, a system comprises: a plurality of remote units and a host including a demodulator.

The host receives the upstream OFDM signals, the tones of the upstream signals substantially orthogonal when received at the host. Portions of upstream OFDM signals from at least two remotes arrive at the host at the same time. The host demodulates said portions. At least one remote transmits to the host using a first tone allocated by the host. The host sends an adjustment signal to the remote to adjust the timing of transmissions to improve orthogonality of the OFDM waveform. After the remote has begun transmission using the first tone but before the remote has completed its transmission, the host allocates to the remote a different tone.Type: GrantFiled: April 20, 2007Date of Patent: April 8, 2008Assignee: ACD Telecommunications Inc.Inventors: Michael J.
