Abstract: A single, common correlation filter (CF) core is provided in a wireless system using CDMA. A plurality of channels with different data rates are provided in the wireless system. The channels provided in the wireless system include the access channel, the maintenance channel, and the traffic channel in which information (e.g., pilot or data symbols or both) is transmitted at the tier 1, tier 2 and tier 3 rates. The data rate for transmitting the information is programmable by digital signal processor (DSP). A user-unique code, such as a PN code, is applied to the information being transmitted in the channels of the wireless system. The information is QPSK modulated and transmitted in any one of the channels at any data rate. The transmitted information is correlated at the smallest data rate (i.e., the tier 1 rate) in the correlation filter (CF) of the wireless system by time multiplexing delayed versions of the PN code to the correlation filter core. The correlated information is then demultiplexed and pilot aided QPSK demodulated. The demodulated information is summed at the proper integer multiple of the tier 1 rate to achieve the tier 2 and tier 3 rates. The three strongest multipaths (in terms of the received power) are selected in a window or time period for optimal information recovery. Furthermore, three outputs from the demodulated information can be provided and combined for temporal diversity. Spatial diversity is achieved by providing a plurality of antennas at each receiver and a single, common correlation filter at each of the plurality of antennas of the receivers in the wireless system.

Abstract: Apparatus and methods of implementing code space search of received signals are described herein. A code space search is implemented as a searcher that perform a subtask that is dynamically reconfigurable at each boundary of an initial integration time. Each particular subtask sets forth a programmable configuration of coherent integration hypothesis that are performed during the initial integration time. The searcher stores the results of the coherent integration hypothesis in a first portion of memory. A search accelerator operates on the initial integration results. The search accelerator can perform coherent integration of various frequency bins of different timing hypothesis, can generate energy values of the coherent integration results, and can generate a non-coherent energy summation. The energy values of the coherent integrations and non-coherent energy summations are stored in a second portion of memory. The ability to reconfigure the subtasks and accelerator operation provides flexibility in search space dimensions.

Abstract: A radio apparatus and base station apparatus that flexibly respond to an increase or decrease in the number of users without being constrained by the number of users. An A-DPCH signal processing section (106) generates dedicated transmission signals corresponding in number to users multiplexed based on the number of users for each sector input from a control station apparatus and outputs the multiplexed signal to a multiplexing section (105). An HSDPA signal processing section (107) selects a transmission destination sector based on an instruction from a base station control section, generates multiplexed transmission data and outputs the multiplexed data to the multiplexing section (105). The multiplexing section (105) code-multiplexes dedicated transmission signals of A-DPCH and packet data in HSDPA communication for each sector and outputs the multiplexed data to a radio transmission section (104). The radio transmission section (104) transmits the multiplexed transmission signal input from the multiplexing section (105) from an antenna (101).

Abstract: The present invention relates to production of a decoded signal (Aτ) based on in an incoming stream of data samples (d(k)) representing at least one downconverted digitized spread spectrum source signal. A number (NM) of the received data samples (d(k)) are divided into a first number (N) of data blocks, where each data block contains a second number (M) of samples. The second number (M) is an integer larger than or equal to two. Each of the data blocks is then correlated with a respective local code replica segment (p(k)) to produce a first number (N) of intermediate accumulation results (ΣI; ΣQ). To enable production of a decoded signal (Aτ) being compensated for a Doppler shift relative to a downconverting frequency for the least one spread spectrum source signal, the intermediate accumulation results (ΣI; ΣQ) are correlated with a carrier vector (s[z]I; s[zQ) expressing such a Doppler shift. However, according to the invention, the carrier vector (s[z]I; s[z]Q) only contains a target number (Z) of carrier values (s1I:sZI; s1Q:sZQ) (i.e. different carrier amplitude levels), where the target number (Z) is smaller than or equal to the first number (N). Normally, the target number (Z) is substantially smaller than the first number (N). Thus, depending on the first number (N) and the target number (Z) for the relevant carrier vector (s[Z]I; s[Z]Q), a number of consecutive results of the intermediate accumulation results (ΣI; ΣQ) are combined into a number of aggregated accumulation results (c1I:cZI; c1Q:cZQ), which is equal to the target number (Z). Thereafter, the aggregated accumulation results (c1I:cZI; c1Q:cZQ) are correlated with the carrier vector (s[Z]I; s[z]Q) to produce the decoded signal (Aτ). The invention is well adapted for implementation of software GNSS receivers.
