An example method may include receiving, at a device, a first frame over a wireless network and constructing a preliminary data portion of a second frame. The second frame may be configured for transmission over the wireless network. The method may also include in response to the receiving of the first frame at the device, beginning transmission of a header portion of the second frame over the wireless network and after the beginning transmission of the header portion of the second frame, constructing, based on the preliminary data portion, a finalized data portion of the second frame for transmission over the wireless network.

Wireless data transmission

A multiple-input multiple-output (MIMO) wireless transceiver with 'N' transmit and receive chains and a bandwidth evaluation circuit, a chain partitioning circuit and a switchable radio frequency 'RF' filter bank. The bandwidth evaluation circuit evaluates both the utilization of the WLAN(s) and any remaining communications channels and determines whether to operate the MIMO chains synchronously as a single radio or asynchronously as multiple radios. The chain partitioning circuit either partitions subsets of the MIMO chains for asynchronous operation as distinct radios or combines all MIMO chains for synchronous operation as a single radio. The switchable RF filter bank is responsive to a partitioning of subsets of the chains into distinct radios to add RF filters to a RF portion of the chains to isolate each radio from one another, and responsive to a combining of all MIMO chains into a single radio to remove all RF filters.

Transmutable MIMO wireless transceiver

A wireless device with multiple antennae and configured to support orthogonal frequency-division multiplexed (OFDM), multiple-input multiple-output (MIMO) communications of a wireless local area network (LAN) over a wireless communication medium on a communication channel. The wireless device comprises: a MIMO demapper configured to receive a packet on the communication channel and to perform both linear together with non-linear decoding processes based on an initial communication channel estimate 'H', and with initial linear decoding of at least a first received symbol in a payload portion of the received packet followed by decoding of remaining symbols in the packet using non-linear sphere decoding, thereby reducing a level of complexity associated with non-linear decoding by extending a time interval available for an initial channel estimate decomposition portion of non-linear sphere decoding to span at least a portion of a n interval associated with linear decoding of at least the first received payload symbol.

A method for automatically detecting a plurality of parameters for a NAND-Flash memory. A first step of the method may include generating a plurality of address cycles for the NAND-Flash memory. A second step may set an address number parameter of the parameters based on (i) a first number of the address cycles generated and (ii) a status signal generated by the NAND-Flash memory responsive to the address cycles. A third step generally includes generating at least one read cycle for the NAND-Flash memory after determining the address number parameter. A fourth step may set a page size parameter of the parameters based on (i) a second number of the read cycles generated and (ii) the status signal further responsive to the read cycles.

Method to detect NAND-flash parameters by hardware automatically

An apparatus comprising a first circuit and a second circuit. The first circuit may be configured to generate a plurality of match signals in response to an incoming data signal. Each match signal is generated in response to different search criteria. The second circuit may be configured to present a protocol indication signal in response to the plurality of match signals.
